Problems with root partition

I've been having issues with my root partition the last few weeks. Everytime I turn off my machine or reboot I get the warning saying umount: device busy and the machine turns off or reboots. During boot I the get the message during "checking filesystems: superblock: FIXED write time in the future" or something similar and when it checks/scans the partition (after every 35th or 37th boot) it fails. I have no idea what is the problem or how to fix it.

OK, there are too many processes to sort through there easily. You shouldn't show that many processes as an ordinary user, if you are not running X. It may be normal if X is running. But I don't think it's right. And we should have used the verbose option, '-v' as well as the '-m' option. The '-m' shows all processes accessing files on that file system. The '-v' will give us human readable output.
I have separate /, /boot, /var and /home partitions. Root is /dev/sda6. From a Linux console I get
$ fuser -mv /dev/sda6
USER PID ACCESS COMMAND
/dev/sda6: root kernel mount /
casey 2676 .r.e. bash
Running openbox, tint2, urxvt, firefox and leafpad, I get
$ fuser -mv /dev/sda6
USER PID ACCESS COMMAND
/dev/sda6: root kernel mount /
casey 2676 .r.e. bash
casey 3391 fr.e. startx
casey 3407 .r.e. xinit
casey 3414 .r.e. ck-launch-sessi
casey 3433 .r.e. openbox
casey 3440 .r.e. tint2
casey 3477 Fr.e. firefox
casey 3481 .rce. dbus-daemon
casey 3482 .rce. dbus-launch
casey 3484 Frce. gconfd-2
casey 3506 .r.e. urxvt
casey 3507 .r.e. bash
casey 3511 .r.e. leafpad
Under the 'ACCESS' heading, 'f' means there's an open file, 'F' means there's a file open for writing. If /var or /home are on your root disk, the list will be longer. The effs don't show unless '-v' is used.
If you run fuser with root priveleges, you get a much longer list, but I don't think you'll need to do that. I think you want to look for processes with the uppercase 'F' and kill those processes. And then you have to find why they are not shutting down properly.
If you install lsof, and then run 'lsof /dev/sda6'it will list all the open files on /dev/sda6. Then to find the process that has /ttt/iii/some_file open, you simply enter 'lsof /ttt/iii/some_file'. to kill the process that has /ttt/iii/some_file open, enter
kill -HUP `lsof -t /ttt/iii/some_file` #Those are backticks
Edit: I'm learning here, too. I'm trying these commandsjust before I write them.

Weird problems with recovery partition

Hi. I just got a new X1 Carbon a few days ago. When trying to install Ubuntu, I messed up the bootmgr. At that point I still had the option F11 for recovery on startup, but choosing it did not give any results and after a restart, the option was gone. When researching the problem, I found this thread:
http://forums.lenovo.com/t5/ThinkVantage-Technologies/Need-help-with-recovery-partition-create-recov...
Since my recovery partition Q was untouched, the steps described in the thread allowed me to restore partitions S and C. So far so good, but now the problems start.
First, the letters of the partitions get messed up after every reboot. I assign Windows7_OS the letter C, SYSTEM_DRV gets S, and Lenovo_Recovery gets Q. Diskpart then lists the drives with correct letters. But after a reboot, they're back to D,C,E, respectively.
Then, when I boot the Windows recovery disk from a usb stick, it correctly recognizes that Windows is installed on drive D. It suggests that there are startup problems, which I tell it to fix. After the next reboot, it does not warn me about startup problems. When I then go to command prompt and enter
bootrec.exe /fixmbr
bootrec.exe /fixboot
then the Windows recovery disk commits suicide. It seems to attempt to fix its own bootmgr. At the moment, both usb stick and hard disk run with grub (Windows recovery on a multiboot installed by YUMI). After I run the commands above, the hard disk still runs with grub, but the usb stick now has bootmgr and fails to boot. I have tried this several times, each time recreating the Windows recovery disk with YUMI, and every time the same result.
F11 option is of course still gone. At this point I'm out of my wits. Any suggestions are welcome.
Solved!
Go to Solution.

In the end I formatted and made a clean install. F11 Option is gone. Recovery partition is still untouched, but I don't think it will be used again. Followed this advice to install a fresh Windows 7 using a usb stick:
http://www.sevenforums.com/tutorials/219487-clean-reinstall-factory-oem-windows-7-a.html#post1839164
Since I did not have access to Windows with administrator rights, I had to use Ubuntu to create the bootable Windows stick:
http://cloud101.eu/blog/2012/03/24/create-a-windows-7-live-disk-from-ubuntu-linux/
The WiFi driver was not included in Windows, so I had to download that in another system, and install manually. From there I could then go online in Windows to download the remaining drivers from Lenovo (after the clean install there's a long list of unrecognized devices).
Since the laptop comes with 4 primary partitions preinstalled I had to merge the SYSTEM_DRV and the Windows7_OS partition in order to create an additional partition for Ubuntu. Then I installed Ubuntu and took control of the startup behavior using EasyBCD.

Problem with replicated partitioning between two BSO db's. version 9.3.0.1

Hi there,
I have a problem with partitioning between two BSO db’s.
I created the partition, it validates and I made an export for the partion definiton(xml file).
Everything is fine if I set this partition up as transparent partition.
This means I can see the data from the src in the trg db as ecpected.
But when I change over to replicated (what in fact I want to do) nothing happens for the trg site - there are still no data. (Yes I have choosen Update all cells.)
I got no error in any way neither AAS nor in the app logs of src and trg.
(Mayby this it important: one src-dimension is mapped to void for the trg.)
Can anyone give me a hint or even confirm this behaviour ?
Thank you in advance
Andre

It sounds like you are doing it all correctly. One thing you might try just to be sure you are not getting any data in the target database is the following:
1) clear the target database
2) Run the replication for all cells
3) Run an export of all data on the target database
See if you get anything in the export file, maybe you are getting some of the data or possibly it is a rollup issue. Just a thought.

Problems with root ( / ) partititon dimension

Everything is on the subject, using conky as a system monitor or scanning my file system with baobab (gnome utility) i see that my / partition has 7.8 GB of files but if i try to search "phisically" these files i can find only 5.5 GB...where are the remaining 2.3 GB?
The partition is formatted with XFS filesystem...
thanks
p.s. Baobab sees 7.8 GB but when i look at the files detail below this number i can find only 5.5 GB like i said before

Filesystem blocchi di 1K Usati Disponib. Uso% Montato su
/dev/sda1 15347840 8182668 7165172 54% /
/dev/sda2 125205652 17447956 107757696 14% /home
There are some words in italiana but i believe you know the layout of the output so it won't be too difficult to understand it.
However it seems that i'm using 54% of my root partition and this is 7.8 GB, 8.182.688 KB

I'm suspecting the cause of that could be update of "filesystem" where "mtab" where with conflict during updating.
As far as I remember I cleaned up it or even removed (probably the stupidest thing I've made for some time ;]). Several restarts later I noticed problems with /home/userDIR.
In the way of trying to repair that I've copied (especially /proc, /sys etc. mount points) and changed "mtab" from my second Arch installation but nothing helps.
I can manually mount /home, /boot and then they appears

It seems a little suspicious that /, /tmp, /boot and /home are all *exactly* the same size and have *exactly* the same ratio of used to available bytes? Or do you expect that?
Do you have dump installed?
As far as I know /proc /sys etc. are recreated on reboot so you shouldn't need to copy them. mtab should be a symlink. Is it? If so, where does it point?
When you say you can manually mount them, how exactly? Does e.g. just mount /home work? Or do you have to use another command?

Problem with Recovery Partition(After i got a Virus)

Hi all,
I am using HP Envy 15 notebook with windows 7 home premium x64-bit installed.I didnt create the recovery disks since i got this notebook and what happened is that i got a virus from the internet but i almost repaired all system faults caused by it but the main problem for me is that it change all main drive folders name into Virus1232 for example (d:\recovery changed into d:\virus1234) and i spent hours over the internet to get the right folder and file names and i got them all but only one file not sure of.My problem is when i enter the Recovery Manager it doesn't detect any my recovery partition(but the virus isnt responsible for any file deletion it just caused some system changes) and just to speak i also corrected the folder and file names in c: drive since they are needed too.
These are the filenames i got in D: drive : bootmgr - BT_HP.flg - CSP.DAT - DeployRp.log - HPSF_Rep.txt - language.ini ; and the filename let is the one im not sure of: "HP_WSD.dat" (it is a zero-byte file).
The recoverymgrdump.txt works right untit "CSBRMgr::GetRPTOOLPartIndex leaving!"
then it tells me :
"Win32 System Info Code = 3, Info Message = The system cannot find the path specified."
and it also say :
"CSBRMgr::HpcdFlgIsExistInUP <UP>:\WINDOWS\hpdrcu.prc does not exist."
I dont know if that is normal but also the deployrp.log gives me this error:
"Package does not exist: c:\RM\Tools\DeployRp\WinPE_LangPacks\64\winpe-setup.cab"
ofcourse there are more errors in both files but i guess those are the most important.
So my question is: could the file attributes in d: drive be responsible for this error(i changed all attrbutes to be system hidden and read only)
OR
If anyone have a solution please tell me what to do.
Thanks.
This question was solved.

Full start up disk... problem with disk partition.

Hi,
Ive got an original blueberry ibook which an ex, who considered himself some sort of high flying computer buff, decided to fiddle with... In his vast wisdom he deemed that my ibook would run better if he partitioned the start-up disk. The result being a slow running laptop, constant warnings that my start-up disk is full, a keyboard that doesnt function properly, hence missing characters and being unable to use the delete key.
The message that comes up warning about the start-up disk being full says that I need to delete stuff to make room so that it can run properly. Ive tried going into the disk utility thing but it wont allow me to restore the disk back to its original state. I dont know a huge amount about computers but I have tried deleting all programs I dont use and having a good clear out but it hasnt made an ounce of difference.
Does anyone have any idea how to get around this problem? All suggestions appreciated.

Hi dancingdryad
The first thing to check is, have you emptied the trash.
Deleting Applications (programs) should not be necessary, rather the space is more likely being taken up by too many of your documents.
The space has been filled up by your own files, generally called documents, but also includes, videos you have downloaded, photos, music. These are files that you have either created or downloaded and these are the things to move.
So look in your Documents folder, in the iTunes and iPhoto applications, for excess photos and music that you can move onto an external drive, or burn to a CD.
And after trashing something, do empty the trash.
If you have a Previous System Folder on the hard drive, you can trash that as well.

Problems with Bootcamp partition solved using program: iPartition

I Had real BOOTCAMP partition problems:
1. I couldn’t see the partition in the startup list
2. I got an error message “missing operating system”
3. All this was a result of adding an extra Mac partition for Mavericks
4. I fixed it all with a program called iPartition from “Coriolis Systems” in the United Kingdom!!!!!!!!!!!!!

Well, you're not alone. Many other users are having the same problem,and it appears that Apple is ignoring the problem. I bought my iMac 27" in June 2010 and installed Bootcamp 3.1 running Windows 7. About every other reboot the gray screen will freeze during bootup and I have to do a hard reboot. Sometimes I get the Disk Read Failure. It is very, very frustrating. The only reason I bought the iMac 27" is that I like the look of it and the big screen; I have no desire to switch to a Mac, as I have too much money invested in Windows development software. I've installed multiple dual-boot systems in other non-Mac systems and never had any problems. I hope Apple stops ignoring the problem and comes out with a fix real soon.

Problems with NSS partition mirroring and pool errors.

OS: NetWare 6.5SP8 latest patches applied
I have an NSS pool that is made up of two 2TB LUNS on my SAN array.
I've been trying to move the pool from the LUNs on my SAN array to a pair of 2TB VMWare disks by using the partition mirror method.
All of the LUNS reside on the same array, but the two original LUNs are attached to an HBA in passthrough mode, so the VMWare infrastructure does not see those LUNS.
One partition mirrored without issue. The second one shows as synchronized yet remained at 99%.
A forum search indicated that a pool rebuild was in order.
I ran a pool verify and rebuild and tried mirroring the "problem child" partition again with the same result.
Before running the rebuild a second time, I removed both mirrored pairs.
I ran a pool verify and rebuild and tried mirroring the "problem child" partition again with the same result.
Last night, I repeated that same process and finally got 100% synchronization.
In the second and third rebuild processes, I got an error message stating that data would be lost if I continued the rebuild. Since I have backup, I continued the rebuild.
About 6 hours after that synchronization finished, I started receiving block error messages for the pool:
NSS-3.00-5002: Pool xxxx/DATA is being deactivated.
An error (20012(nameTree.c[45])) at block 536784421(file block -536784421)(ZID 6) has compromised volume integrity.
The pool deactivated itself.
I reset the server and when it mounted that volume, I continued to receive the errors.
I deactivated the pool, put it in maintenance mode and started another pool rebuild, this time with the /purge option.
I did not remove the mirrored pair before the rebuild started, so I have the one partition that gave me no problems un-mirrored and the partition that did give me problems is mirrored.
I don't know if that will have any affect on the rebuild process or not.
My questions are:
1) Will the fact that the pool is only half-mirrored be an issue for the rebuild?
2) Is there any other option in the rebuild process that I should have added?
3) Is the fact that I'm mirroring to a VMFS disk an issue? I could create a new pool/volume on those VMWare disks and use the server consolidation utility to copy the data between volumes, but my desire to avoid that was the reason to use the mirror process in the first place.

The difference between a sledge hammer and a Q-Tip is that you do a lot less damage with a Q-Tip.
Everything has been messed with to the point where it would be impossible for any other advice than make a new disk, make a new pool, make a new volume, and do your restore. Then, when all the data is restored without error, move the OLD DATA: volume out of the way and put in the NEW DATA: volume.

1. God only knows. It should not.
2. No. I think its an issue of doing too much, to quickly. It is unlikely a pool rebuild would "fix" a mirroring problem. I would not have gone ahead with a pool rebuild with mirroring broken.
3. A disk is a disk. Perhaps there is some underlying issue with the VMDK. How is it provisioned? Is it out of space? Buggy edge cases of having an extactly 2TB VMDK? Who knows.
The mirroring happens at a layer below the pool level. So I have a hard time understanding a how a rebuild would help mirroring unless the pool is really bent to begin with.
Again, the state of the current DATA: volume would be in question after all that fiddling, even if you can get it to work would you really trust it? I would not. I would recreate DATA: from backup on whatever new partition you want and chalk it up to experience. You can minimize the pain of that by restoring to a differently named volume and then renaming the volumes after you confirm proper operation.

Problems with Winclone/Partition space

hello, I have a MBpro 08 edition and have a partitioned disk that is running XP. It is running really low on space, so I downloaded Winclone and made an image of the partition. The problem is that whenever I restore the image to the new partition which I have made 25 gigs, XP says that I still am low on disk space. It seems like Winclone is just restoring to my old partition of 10 Gigs, which is not enough space. Can anyone help me with this? Thanks in advance for taking the time to look into this.....

Stefan,
Hello, thanks for your assistance.
I think I have read about this in some other posts. I am running a cloned version of the original XP version - so I can still use XP it is just running really low on space - if that makes sense?
Yep, makes sense: your XP is still up an running but running out of disk space
So when I convert to the NTFS file system do I open my XP partition and then follow the instruction on your link and then restart? After that I am assuming that I clown the converted NTFS version and then restore it?
Yes, the convert command has to be used while running Windows. You will get the following mesage when running convert
"Convert cannot gain exclusive access to the drive letter drive, so it cannot convert it now. Would you like to schedule it to be converted the next time the system restarts? <Y/N>", since convert needs exclusive access to your Windows partition.
Answer (Y) for yes and reboot to Windows so that the convert process can start.
Once finished a second reboot to Windows might be a good idea.
After the conversion to NTFS was successful you can use WInClone again to backup the Windows partition and when you restore this backup you can use the resize function of WinClone.

Installing a SSD Samsung 830 Drive on my 520 - Problem with Recovery partition

Hello,
I am installing a 128GB Samsung 830 SSD on the W520, and i've put the original 50GB HDD on a HDD bay replacing the DVD/CD. bay.
I did a system recovery on the HDD, to put it on its original states. Then I used Acronis True Image HD to clone the HDD to the SSD. I have the main partition on the SSD along with the Lenovo_recovery partition. I then install the SSD on the HD slot, and start the PC. No problem till there. It starts, and the machine works fine.
I then do a system recovery from the HDD, and the recovery process goes to the end, but when the system restarts, I have a crash and it asks me to introduce the windows recovery disk. But I cannot starts anything anymore.
If I reinstall the 500GB HDD, it start no problem.
Any idea? Thank you for your help!

Really? Then how did you get the Samsung SSD in there to begin with. Look, you got two choices here: 1. Return the SSD for a refund, or 2. Find a Windoes PC & update the firmware.
Why you'd purchase an SSD, to use in a Mac, whose firmware can only be updated using a Windows computer, makes no sense to me.

Problem with merging partitions

Hi all,
I am having a bit of trouble partitioning the HD on the MBP. I hope you guys can help me. I would like to reformat the drive and have made a partition entitled "Backup" (see image link above) to store the files I need.
Now, I would like to merge "Macintosh HD" and "Macintosh HD 2" together but it won't do it. I have tried in recovery mode and I have tried deleting Mac HD 2 and pulling down Mac HD. Both methods did not work. Appreciate any help. Thank you and sorry if this problem has been posted in the forum.

Something is messed up in the partition map which means you will have to repartition the entire drive from scratch.
Drive Partition and Format
1. Boot from a bootable external drive. Open Disk Utility.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Apply button and wait until the process has completed.

Problem with bitmap partitioned index

My order table (3.6 M rows) has got 4 partitions (one per year). I've defined 24 LOCAL BITMAP INDEXES on the data (DSS environment); every index is built on one column.
The cardinality of these columns is quite various (from 10% to 80%) - I know in some case the use of bitmap index is not OK -.
The table is manipulated in this way:
- Nightly it has about 5K new rows inserted.
- All of this rows have update after insertion (only some of this update are referred to indexed column).
- Early in the morning the partition table referred to actual data, is analyzed with COMPUTE STATISTICS option.
- During the day the data are queried thousand times.
The problem is:
1. Before table/index partitioning all the indexes of the table were BITMAP too, and their size were acceptable; these size did not grow up to much during the time. We use to rebuild index once at 2-3 months.
2. After table/index partitioning some of the bitmap indexes related to the partition that contain actual data, get poor in few days. Their size grow up very quickly (about 16mb at day) and they can allocate 100 times more space than before partitioning. So, I must rebuild these indexes / partitions once at 2-3 days. I have checked the distinct values of poor indexes column, and there is not correlation between cardinality and growth (I mean, this problem happens on index with low cardinality as well as high cardinality).
3. I have the same order table in another schema with the same indexes and similar number of rows (1.7 M). Any of these indexes have strange growth. (I.E.: size of index on AGENT column is normally 2Mb; the poor index is about 200Mb after 4 work days).
We work with 8.1.7.2 on Windows 2000.
Does anyone have any idea about my problem?
Thanks in advance L.

I create 2 different bitmap join index:
CREATE BITMAP INDEX lsa.AAB_V_ARTICOLO_MARCA_IDX ON LSA.AAB_VENDUTO(MARCA)
FROM LSA.AAB_VENDUTO vv, LSA.AAB_ARTICOLO aa WHERE vv.articolo_id=aa.articolo_id;
CREATE BITMAP INDEX lsa.AAB_V_CLIENTE_TIT_STUDIO_IDX ON LSA.AAB_VENDUTO(TITOLO_STUDIO)
FROM LSA.AAB_VENDUTO vv, LSA.AAB_CLIENTE cc WHERE vv.cliente_id=cc.cliente_id;
What happens if you just create two plain bitmap indexes without the join?
CREATE BITMAP INDEX lsa.AAB_V_ARTICOLO_MARCA_IDX ON LSA.AAB_VENDUTO(MARCA);
CREATE BITMAP INDEX lsa.AAB_V_CLIENTE_TIT_STUDIO_IDX ON LSA.AAB_VENDUTO(TITOLO_STUDIO) ;You can also go with normal indexes on the FK rows (cliente_id) and the optimizer can do a bitmap conversion from normal index to bitmap index if needed. Are the column values evenly distributed? If not you might need to go for some column histogram. but I don't have the impression that this is really useful in your case.

Problem with root and constructors

hello guys,
i have serious problem, its 2 days i am trying to do something about it,
i have some object inside object inside another object,
if in their constructors i write:
MovieClip(root).someVar
(or function)
its not working!
it works only i regular functions,
i cant even call a egular function from the constructor,
please help my guys, i really need this!
thanks alot!

function YourDisplayObjectClass(){
// this is the contructor
// trying to reference MovieClip(root) or stage will trigger a null ref error
// because YourDisplayObjectClass instance isn't added to the stage, yet
this.addEventListener(Event.ADDED_TO_STAGE,init);
private function init():void{
// from here you can reference displaylist items.
trace(MovieClip(root),stage);

Dv 6-6170 ee problem with recovery partition

my recovery partition isnt working when i try to start it by F11 a message of failure of allocation of the partition appear ,i had made an extra partiton using a tool then when the recovery problem appeared i removed this partition and when i tried to set the partition as an active one i cant press it because it is deactivated.
in the manager window it shows that i have 4 partitions C,System,Recovery,Hp tools is this right and how can i reactivate my recovery to work properly,plz advice me.
This question was solved.
View Solution.

After applying the changes- restart the laptop at least once. Then shutdown and restart after 1 minute--tap F11 to check if Recovery is working.
