Increase root filesystem size with VxVM

Hi All,
Can i increase the root fileystem size in solaris 10 after encapsulating the root disk into VxVM.
Thanks
---MGP---

I wouldn't try it.
If you have a mirror, I'd drop the mirror, copy everything over to the mirror disk (in normal, contiguous slices), then redo the VxVM encapsulation.
Root filesystem cannot be discontiguous, no concats, stripes, raid5s, only mirror. So growing is difficult unless the space is already past the end.
Easier to copy to another disk, reset the bits (/etc/system, /etc/vfstab), then boot from it.

[SOLVED] df -h does not reflect true root filesystem size

Why does df -h show root filesystem as being only 20G?
df -h
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/cryptroot 20G 15G 4.6G 76% /
dev 7.7G 0 7.7G 0% /dev

/dev/sda1 239M 40M 183M 18% /boot
tmpfs 1.6G 8.0K 1.6G 1% /run/user/1000
That is what my df -h output looks like. My setup is full disk encryption using dm-crypt with LUKS, per the guide on arch wiki. I basically created one /boot partition and left the rest of the disk to be an encrypted partition for the root filesystem. So why is my system complaining about (and acting as if it's running out of space)? Have I forgotten something?
Thank you for reading this. Let me know if you need any more logs or info on my setup - I realise I haven't provided very much info here, but I can't think of what to provide.

Increase root filesystem in ldom

Hi
I have a ldom having a flat file /ldoms/ldom1-data in the backend used as a virtual disk c0d2s0 for data In the ldom .Now this virtual disk is running out of space in the ldom How can I increase the size of this filesystem in the ldom or my only option is to create another file of bigger size in the primary domian ,export it to the ldom as a new Virtual disk ,parttion it in the ldom and copy the data from the old disk to the new

After you increase the page size with Ctrl/plus, is there a way to keep the new setting?

''Duplicate post, continue here - [https://support.mozilla.com/en-US/questions/845611]''
My new laptop has great features but a smaller screen. Changing the resolution makes everything look awful. Using Ctrl/plus to increase the page size in Firefox solves the problem, but you lose the new setting when you go to a different page. Is there a way to keep the new setting until you reverse it with Ctrl/minus ?

There are some add-ons that can be used to change the zoom level on all sites, for example:
* NoSquint - https://addons.mozilla.org/firefox/addon/nosquint
* Default FullZoom Level - https://addons.mozilla.org/firefox/addon/default-fullzoom-level

How do you increase the video size with a button?

I'm trying to set up a demo for a meeting. I want to show how
you can increase the size of the video.
Example:
http://video.google.com/videoplay?docid=-1532523169750528353
There are two buttons in the bottom right corner of the
player that will increase the video size.

I havn't tried this but I would thinkg that this could work:
If you have a video object on your stage (the object that the video
actually plays in) you could probably make a button that simply
changes the dimensions of it such as:
setProperty("theVideoPlayer",_height, 240);
setProperty("theVideoPlayer",_width, 320);
The movie should adjust to fit the screen, however if you
make the movie larger than or a different aspect ratio than the
original, it will be blurred or distorted respectively. Make your
original movie, therefore, at the largest size you want it to be
seen. Keep the aspect ration the same always.

Broken root filesystem

Hello,
I've got two eeePCs, both running arch, and yesterday I updated packages and manage to break both of them
They've got a 8GB SSDisk per each, on which only Arch is installed.
The fisrt one has got a boot partition (/dev/sda1) on EXT2, and a root (/dev/sda2) on EXT4.
When booting, kernel gets loaded but it panicks saying root filesystem cannot be mounted.
I cannot even mount the root partition using an Arch 2009.08-core-i686 written on an USB stick: the boot partition (/dev/sdb1) works fine, but mount fails on /dev/sdb2, and also fsck says that /dev/sdb2's superblock is not valid: bad magic number. Not even the backup superblock can be used...
Since everything was working fine last time I used the eeePC, I halted it correctly and nothing bad happened to it meanwhile, I'm hoping I didn't lose the filesystem and my data...
How could I check what the problem is?
The second machine (I haven't got it with me at the moment, forgot it home... as soon as I get there I'll boot it using the USB stick) should have only one partition, containing the root filesystem, partitioned with NILFS2.
If I recall correcly GRUB cannot even load the kernel: maybe it stopped supporting NILFS2 filesystems? Anyway unless I won't be able to get my data from Arch live, this is not a big problem...
EDIT: I noticed two other similar threads... Maybe last upgraded broke "esotic" filesystems?
Anyway I cannot mount the EXT4 FS even from Arch Live (while it looks like the others can), and this sounds pretty weird to me...
Last edited by peoro (2010-02-04 18:06:36)

Actually I don't think it's some problem like that...
After I last halted the system (and the halting process went fine, didn't have to force anything) nothing happend to the machine (didn't even move it)... Besides it's not an old machine, I've only got it for a few months (consider that this arch is the first OS I installed on it, and when I installed it ext4 was already out): it's highly unlikely that it reached the writes limit...
Moreover it looks like other users had got similar problems with filesystems the same days:
http://bbs.archlinux.org/viewtopic.php?id=90179
http://bbs.archlinux.org/viewtopic.php?id=90292 (not sure how related this is, anyway makes me think something about filesystems/partitions happend...)
@leberyo: what FS were you using?

Increase of Stack size impact

Hi there,
Please, what is the impact of increasing the Stack size with the -Xss option for the whole system. is there any relationship or formula between -Xms, -Xmx and -Xss options.
Is it necessary to increase the -Xmx option When i increase the -Xss option.
I'm using Weblogic 9.1 within a machine of 16GB under AIX 64bits and IBM JVM. My parameters are : -Xms=-Xmx=1GB and i think pass the -Xss to 1MB because i get many StackOverflow exceptions.

Increase root partition on ufs filesystem

Hello
we have a virtual solaris vm with ufs the disk has become to small..
we have increased the vmfs but we are having problems increasing the filesystem as format only sees the old size.. fdisk does not seem to offer the possibility to expand the partition to its maximum size.. is it possible to change the label of a solaris partition so that it takes into account all the space that is available for it?
why fdisk does not see there is unallocated space.. i could create a second partition and mount it to other directory perhaps.
thank you.

Hi.
Solaris on X86 system placed on special general dos partittion.
fdisk - used for first level. On this level you can create one ( and only one) partition with type Solaris
and can create some additional partitions for other OS.
format - used for second level. It create additional partittions on solaris's partitions on first level. This label also store original size of disk.
So you need:
1. Increase Solaris partition on first level, using fdisk
2. Check that format detect new size of disk and increase/create new.
In case mistake on any steps - you lost data.
This problem correspond only for root fs and UFS.
On my choice - create addtional virtual disk and just add it to system.
For new disk use gpt (efi) type of label.
Regards.

Sorry, can't be done.
If it was any other filesystem than root, you could do by using SVM.
But root filesystems can't be stripes or concats. Only simple mirrors.
So SVM isnt going to work.
If the spare space was after the partiton. You might have been able to do it by the "dirty" method of manually expanding the partition and using
growfs to expand it. You would have had to do it by netbooting or cd booting since growfs can't be used on the current root.
But in any case, you can't do that either since the space if before the partition not after it.
So, reinstalling is your only option..
Well, If you have a spare disk, you might be able to copy the filesystem over to a larger partition on the other disk, growfs it and boot off that instead.
You'd want to try it on a test systen first...

Is there any way to increase the font size in the Creative Cloud. Using a Lenovo Yoga 2 with 14" screen and care barely see the menus.

In short, no. There is no fix yet. They only barely acknowledge there is a problem. The "fix" is to enable 200% UI scaling which makes everything comically huge and unusable. This is pretty much of a joke. A really, really EXPENSIVE joke.

How increase external disk size used for an existing file system, Solaris10

Configuration:
Server: Sun T5220
S/O: Solaris 10 5/08 s10s_u5wos_10 SPARC
Storage: EMC AX4-5
EMC PowerPath: PowerPath Version 5.2
I have the following scenario:
In AX4-5 storage array, I created two LUNs into RAID Group 10, with Raid Type1/0:
LUN 101: 20Gb
LUN 102: 10Gb
Both LUNs were added to Storage Group (SG1) that includes two Servers (Server1 and Server2); both servers have Operating System Solaris 10 5/8 and Power Path.
The servers detect both LUNs across two paths. With Power Path were created a virtual path (emcpower0a, emcpower1a) to access to each LUNs respectively.
We have mounted two file system /home/tes1 over emcpower0a -> LUN101 and /home/tes2 over emcpower1a -> LUN102.
Filesystem size used avail capacity Mounted on
/dev/dsk/emcpower0a 20G 919M 19G 5% /home/test1
/dev/dsk/emcpower1a 10G 9G 1G 90% /home/test2
I want to increase the space in file system /home/test2, without lost the information that I have stored and using the same LUN, LUN 102. To do this I start with the following steps:
1- Create new LUN, LUN 103 with 15Gb into RAID Group 10. Result: OK, I have available space in RAID Group 10.
2- Add LUN 103 to LUN 102, using concatenation option. Result: OK. This action creates a new metaLUN with the same characteristics of LUN 102, but with new space of 25Gb.
After to do these actions, I want to know how Solaris recognize this new space. What I need to do, to increase the size of file system /home/test2 to 25 Gb. Is that possible?
I reviewed the description of each disk using format command, and the disks not have any change.
Could anyone help me? If you need more detail, please do not hesitate to contact me.
Thanks in advance.

Robert, thank a lot for your know how. You helped me to clarify some doubts. To complete your answer, I will add two more details, based on my experience.
After to execute, type -> auto configure and label, the disk was created with different partitions like root, swap, usr, like this:
Volume name = < >
ascii name = <DGC-RAID10-0223 cyl 49150 alt 2 hd 32 sec 12>
pcyl = 49152
ncyl = 49150
acyl = 2
nhead = 32
nsect = 12
Part Tag Flag Cylinders Size Blocks
0 root wm 0 - 682 128.06MB (683/0/0) 262272
1 swap wu 683 - 1365 128.06MB (683/0/0) 262272
2 backup wu 0 - 49149 9.00GB (49150/0/0) 18873600
3 unassigned wm 0 0 (0/0/0) 0
4 unassigned wm 0 0 (0/0/0) 0
5 unassigned wm 0 0 (0/0/0) 0
6 usr wm 1366 - 49149 8.75GB (47784/0/0) 18349056
7 unassigned wm 0 0 (0/0/0) 0
This was not convenient because all information stored appear in the first slice and growfs not work if appear root or swap slice into the disk, for that reason was necesary to recreate manually every slice with partition command. The final result was this:
Part Tag Flag Cylinders Size Blocks
0 unassigned wm 0 - 49149 9.00GB (49150/0/0) 18873600
1 unassigned wu 0 0 (0/0/0) 0
2 backup wu 0 - 49149 9.00GB (49150/0/0) 18873600
3 unassigned wm 0 0 (0/0/0) 0
4 unassigned wm 0 0 (0/0/0) 0
5 unassigned wm 0 0 (0/0/0) 0
6 unassigned wm 0 0 (0/0/0) 0
7 unassigned wm 0 0 (0/0/0) 0
Now, execute again the label command to save the new information.
Mount file system and execute:
growfs M file_system mount_point to expand the file system to 9Gb.

[LVM] Shrinking /home to increase /root failed [solved]

Hi there,
Before doing anything wrong and risking data loss, I will better ask for your advice. I used the following commands to shrink my /home partition in order to increase /root:
# vgchange -a y
# e2fsck -f /dev/VolGroup00/Home
# resize2fs /dev/VolGroup00/Home 205G
# lvreduce -L 206G VolGroup00/Home
# lvextend -l +100%FREE VolGroup00/Arch
# e2fsck -f /dev/VolGroup00/Arch
# resize2fs /dev/VolGroup00/Arch
The initial size of the logical volume Home was 208GB according to lvdisplay. The volume Arch corresponds to my /root.
All commands completed successfully. However, on boot I get the following error:
Home: The filesystem size (according to the superblock) is 54525952 blocks
The physical size of the device is 54001664 blocks
Either the superblock or the partition table is likely to be corrupt!
Home: UNEXPECTED INCONSISTENCY: RUN fsck MANUALLY
I booted from a live disk and tried to run fsck manually. But it aborts with the same error.
What am I advised to do now?
Thanks!

Filesystems don't like it when parts of their storage go missing. You have to get the missing parts back.
Find your LVM backups / archives ( /etc/lvm/archive ), see if there is a file that says "created *before* lvreduce -L 206G VolGroup00/Home". That file would tell you where the /home partition was allocated before you shrank it.
You can use vgcfgrestore to get back to that state of things. At that point your /home should be accessible again - or at least fsckable. (But of course the /root is broke then - can't have both).
1) Before doing anything else, make a backup of your /root files if you need one
2) Free some space so you can use snapshot before you fsck. If fsck messes up you really are in trouble.
The real interesting question is what went wrong with the shrink in the first place. Your commands look like they should have worked. Most likely the resize2fs failed somehow? since it still believes itself to be 208GiB large.

CentOS based linux VM running on Hyper-v : Checking root filesystem fails when kernel switches having old PV(para virtualised driver based on 2.6.32 linux kernel) to new PV(which is equivalent to linux integration component 3.4)

hi all,
I am running a CentOS base VM on top of Hyper-V server. I upgraded PV drivers of Hyper-V in linux kernel 2.6.32 in order to support
Windows Server 2012, then i am hitting below issue on Windows Server 2008 when kernel switches from old PV(which is 2.6.32 based) to new PV(which is equivalent to linux integration component 3.4).i
am hitting following filesystem check error messages :

The superblock could not be read or does not describe correct ext2 filesystem. If the device is valid and it really contains an ext2
filesystem(and not swap or ufs or something else),then the superblock is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 <device>
: No such file or directory while trying to open /dev/hda2
*** An error occurred during the filesystem check.
*** Dropping you to a shell; the system will reboot
*** When you leave the shell.
Also, when I go to the repair filesystem mode. I found out the strange behaviour when i ran those command :

-> blkid contains duplicate UUID, below are the output.
~~
This situation is classic problem "
use hv_storvsc instead of ata_piix to handle the IDE disks devices ( but not for the DVD-ROM / CD-ROM device handling)
~~
For compare, see example "good situation":

( only CD-ROM and 1( one) IDE disk connected to ATA)
~~
regarding ata_piix.c patch . . .
As far as i understand this patch , it ignore ATA devices on Hyper-V when PV drivers(CONFIG_HYPERV_STORAGE=y) are enabled.
~~
Yes:
ignore ATA-HDD ( but not ignore ATA CD-ROM ) on Hyper-V when PV drivers(CONFIG_HYPERV_STORAGE=y) are enabled.
~
this patches need be backported:
cd006086fa5d ata_piix: defer disks to the Hyper-V drivers by default
and its prerequisite
db63a4c8115a libata: add a host flag to ignore detected ATA devices
~
~~
P.S.
Are You do this:
==
As temporary solution, increase on 1-2 Gb size all .vhd connected to IDE bus
( but not increase size of partitions inside disks)
==
? fsck write message a-la: "no error in file system" ?

Re-arranging the filesystem sizes in Solaris 10.

Hi,
I have done a fresh install of a machine using the CDs. I would like increase many of the file system sizes including the root filesystem.
It is very easy in HP UX using the utility Ignite UX.
In Solaris, do we have any way to do a system backup and while restoring have a different filesystem sizes.
I have heard about flar not sure we can use that images for the above activity.
If you know or done this earlier let me know the steps you have done.
Thanks

Found on this form the answer:

My mistake was I renamed the file /var/sadm/install/productregistry...this has to be moved or removed.
Thanks.
