Cannot write to RAID

We have a Xserve RAID that we have been using for years with no problems. We put in a Promise RAID in December and have reoriented the XserveRAID for different uses. Since then we have had problems with the Apple RAID. After running for a few days it will not allow anyone to write to it. If you try to create a folder you get error -50. If you try to drag a file to you it you get a message that the file has an illegal file name.
When we changes the use of this RAID we made a number of configuration changes.
Original setup: Split into 4 slices and allocated to 3 Xserves with a Qlogic fibrechannel switch and LUN masking. Firmware 3.x.
Current setup: Connected to an Xserve Intel with a new Fibrechannel card (in the Xserve), no LUN slicing, the RAID is connected directly and no Fibrechannel switch involved. Firmware 1.5.
When I check the log I see a number of entries for this morning from 7:25:40 AM to 7:27:06 AM (as far as I know no was was accessing the network volume that is this RAID at the time). The entries show:
RAID Controller 1 Fibre LIP
RAID Controller 1 Fibre LIP
RAID Controller 1 Fibre Link Down
RAID Controller 1 Fibre LIP
RAID Controller 1 Fibre Link Up
RAID Controller 1 Fibre LIP
When I look at the uppder controller it shows link up, but I guess that the link was down for over a minute and this caused the problem.
My first thought is to upgrade the firmware to 1.5.1 since we no longer need LUN mapping. I am only using the left side of the RAID so should I consider swapping the upper and lower controller cards or taking a controller card from our parts kit?

Hi macman1977;
The invalid sibling link error is a serious problem with the directory on that disk. The only way I know to fix this error without reformatting is DiskWarrior. Never having used RAID on my Mac, I don't know if DiskWarrior works with it. You might call Alsoft technical support and ask them for help on this problem.

Cannot get software RAID-1 going on root (/) on Sun V240's

Hi All,
I for the life of me cannot get software RAID-1 going on the root file-system. I've followed the instructions in Solaris Volume Manager Admin. Guide and I think I'm doing it right. This is in a Sun V240 with two 137GB drives.
I basically do the following:
Disk0 - c1t0d0s0
Disk1 - c1t0d1s0
prtvtoc /dev/rdsk/c1t0d0s2 | fmthard -s - /dev/rdsk/c1t1d0s2
prtvtoc /dev/rdsk/c1t1d0s2 (Double check that disk 1 looks like disk 2)
metadb -af -c 2 /dev/rdsk/c1t0d0s3 /dev/rdsk/c1t0d0s4
metadb -af -c 2 /dev/rdsk/c1t1d0s3 /dev/rdsk/c1t1d0s4
metainit -f d10 1 1 /dev/rdsk/c1t0d0s0
metainit -f d20 1 1 /dev/rdsk/c1t1d0s0
metainit d0 -m d10
metaroot d0
lockfs -fa
reboot
Before I reboot, I do a metastat and it shows the following:
# metastat

You created to many metadatabases..
I'm not kidding, you did. You created 8 which i suspect trigged a bug which currently exists in Solaris 9 / Solaris 10.
This bug occours on the following disks: MAT3073N, MAT3147N, MAT3300N and ST373207LC, if you have any of those disks in your system (can be determined with iostat -En) you must use less than 8 replicas.
Check out bugreport 6244431, if you got a sunsolve login linked to a contract number.
You could try and boot up the system from a cdrom or similar and add "md_devid_destroy=1;" to the /kernel/drv/md.conf file above the 'Begin MDD database info' line.
hopefully your system will come up after this, if it does the best workaround is to remove a few replicas, the above line from md.conf and reboot.

Mid 2007 iMac SSD in optical bay - cannot write to last block of device

Hi All,
I've just replaced my optical drive in my 20" mid 2007 iMac (Dual core, 2.4 Ghz, 2 Gb RAM running Mavericks) with a solid state drive (Crucial MX100). The plan is to transfer my boot disk to this drive while keeping my 1 Tb HDD for media and such.
I followed the ifixit guide and it all went smoothly, however when I try to partition or erase the new SSD using Disk Utility, it tells me "Operation failed - cannot write to last block of the device". After googling, I found some answers here that suggested the optical bay cable may be faulty, so I bought a replacement and swapped it in, but no such luck, same problem. I also saw some threads suggesting that the boot disk should be in the original hard drive spot, but since this isn't the boot disk (yet) this shouldn't be the issue.
My computer recognizes the new SSD but won't allow me to partition it. Any suggestions on how to proceed?
Thanks!

3. The new disk is just bad.
OK. If that's the case, I'll just get another disk.
Lots of problems with that hybrid drives on Mac's on these forums, get another one that's 7,200 RPM and from Western Digital, not Seagate.
With a 7,200 RPM you get more performance across the entire drive, not just what's cached in the small flash portion of the hybrid.
https://discussions.apple.com/community/notebooks/macbook_pro?view=documents#/
1. Hybrid drives: I'm on number 8 in 6 different machines, no problems at all, what happens when you try?
2. The OP is not using a Hybrid.
3. Lot's of problems with WD drives not booting on these forums though.

Cannot write to transaction log "C:\Program Files (x86)\SAP BusinessObjects\sqlanywhere\database\BI4_Audit.log

Hi friends,
My server Intelligence Agent (SIA) can not start because the database service "SQLAnywhereForBI" can't start also. I got the following error :
"I . 08/09 20:35:06. A read failed with error code: (1392), Le fichier ou le répertoire est endommagé et illisible.
E. 08/09 20:35:06. Fatal error: cannot write to transaction log "C:\Program Files (x86)\SAP BusinessObjects\sqlanywhere\database\BI4_Audit.log"
E. 08/09 20:35:06. unable to start database "C:\Program Files (x86)\SAP BusinessObjects\sqlanywhere\database\BI4_CMS.db"

I. 08/09 20:35:06. Database server shutdown due to startup error "
inside the database log file.
Please, can you help me

I found the solution by following the advice given on the following forum:
http://evtechnologies.com/transaction-logs-on-sybase-sql-anywhere-and-sap-businessobjects-bi-4-1
In fact, I crushed the BI4_Audit.db and BI4_Audit.log files and I replaced with others that I got from another machine where I installed BO again and where the files are not corrupted . After I logged in to the CMS database by executing the command in the command line:
dbisql -c "UID = DBA; PWD = mypassword; BI4 Server =; DBF = C: \ Program Files (x86) \ SAP BusinessObjects \ sqlanywhere \ database \ BI4_CMS.db."
Once connected, I start the command:
alter database 'C: \ Program Files (x86) \ SAP BusinessObjects \ sqlanywhere \ database \ BI4_Audit.db' alter log off;
The query runs successfully.
And that's good, I can be connected to BO smoothly.
Thank you again Eric

My first gen ipod mini does no longer sync with itunes 11.0. It says "cannot write or read". Ist this the end?

My first gen ipod mini (that I use in my car) does no longer sync with itunes 11.0. It basically says "cannot write or read". Is this the "end of life" of that ipod?

You mean you can't get to the Summary pane?
If you have iTunes 11 turn on the Sidebar. Go to iTunes>View and click on Show Sidebar. You can also do a Crtl+S to show the sidebar. The sidebar is where Devices appears. and Control+B to show the Menu bar

Cannot Write or Read to disk Error during iPhone 3g 3.1 sync

Searched the forum with no luck. Just upgraded to 3.1 on my 3G and I cannot sync without it stopping with the error - Cannot write or read disk. It seems like its almost random on what file it picks to stop on - the file plays fine in iTunes 9. Any suggestions?

Hi,
Restore the Touch. There is no easy way to remove files from an iPod as it classes media on the iPod as "read-only" - There are software products that can be used to remove media from an iPod, but it is not an official method and you risk causing more damage.
If you really need the files on the Touch then use Google to find a program to remove files, there are a few, but do so at your own risk!
Kind regards,
Peter.

Cannot Write to USB Drive after it wakes up

I have a couple of external USB drives. Once one of them goes to sleep, I cannot write to it or eject it when it spins back up. When I try to copy and file to it the files seems to copy ok and when it's just about finished it errors out. This happens with the finder and with Pathfinder as well. If the drive sits and OS X spins it down I can't write to it or eject it when it spins back up. I just get the usual drive is busy, can't eject and any write attempt fails. I have to force disconnect it and reconnect it for it to function normally again. Tried a permission repair and that found no problems.
Any ideas?

Ok. More details. Apologies for the lack of them to start with.
The Case is a Vantech USB/SATA HD Dock. It has it's own power (i.e. it is not powered by the bus). The Drive in it is a Western Digital 1TB Caviar Green. It has done this on all USB ports and with any computer it has been connected to. Mac computers any way, I have connected it to a windows box at work, but not long enough for the problem to manifest it self. Unfortunately I don't have a Mac I can hook it up to directly via SATA to see if it is the enclosure. I found another SATA enclosure here at work to try it with tonight. It's not the computer going to sleep that is causing the problem. It the OS spinning down the drive.
I get this in the console log when I try and unmount the drive via the finder:
20/07/09 11:17:00 AM /System/Library/CoreServices/Finder.app/Contents/MacOS/Finder[3426] StatusMonitor::volumesChangedCallBack returned -47

Cannot Write to USB Stick

I can copy from USB sticks but cannot write to USB stick.
I have tried various USB sticks to ensure I wasn't using an old stick or a damaged stick but nothing works.
I have tried formatting the sticks differently, i.e. FAT32, Mac OS Extended etc but still doesn't work.
The files I am trying to copy are only 200KB onto an empty, newly formatted 16GB stick.
I have checked and permissions for the stick is Read/Write.
Any help appreciated.
Thanks.

Does nobody read OP anymore? USB had the Arch installer on it, which involves some non-standard partitioning.
@radoslav192
Manually re-partition your thumb drive with fdisk, etc., then format the partition.
Edit: had to remove the log from my eye.

Boot Camp - Windows can read Mac disk, but cannot write to it

iMac OSX Snow Leopard. Windows XP.
Can anyone help me resolve this. I have installed Windows XP using Boot Camp. The Windows folder is 31GB using FAT32.
Windows can read from the Mac disk, but cannot write to it (I get an ACCESS DENIED) error.
I have checked that permissions are set to Read/Write on the Mac, and have run permissions manager to check all is well. I have also tried deleting and reinstalling Windows, and creating a second User on the Mac.
When I boot into OsX then I can write to the Mac hard disk from another (Windows) computer on a network.
I think this did work initially, and it stopped working when I changed the computer name on the Mac (though this might be a red herring -- but it did definitely work OK yesterday).
I'm a new convert to Macs, but am experienced with Windows machines, and I would appreciate any pointers.

This is by design. The driver that allows access to the HFS partition is read-only. This prevents any possibility that Windows viruses could become an attack vector against the Mac OS. If you need to transfer files between Mac and Windows, you can always use an external hard disk or memory stick formatted as FAT.

9.2.0.6 OUI cannot write to its own installation directory

I would like to install the 9.2.0.6 patchset on a freshly installed 9.2.0.4_linux_x86_64 (AMD). The system is RedHat EL AS 3. I have installed j2re1.4.2_07 (because the Java brought by Oracle does not even start the VM ...) and edited the ./install/oraparam.ini to use our own JRE.
runInstaller tells me that all system requirements are met. But - alas - OUI says that it cannot write into the directory that it created itself (tmp/OracleInstall...). The rights matrix of this directory is drwxr-xr-x oracle oinstall, even if I set umask to 0000. There are several GB free.
The last message is
: file or directory not found
What is going on here (or rather what isn't)? What file is OUI looking for?
Thanks in advance for kind replies

Ivan,
the rights for /tmp were already rwxrwxrwt. Even if I remove the sticky bit, the error remains. I have the strange feeling that this is not a rights problem. Do you have any idea what
: file or directory not found
is supposed to mean? What file is OUI looking for? Does OUI 10.1.0.3.0 check for temporary files of other OUI versions (e.g. OUI 2.2.0.18.0 bundeled with Oracle 9.2.0.4)?
I think I will start from scratch: remove and reinstall 9.2.0.4 and then try the patch installation again.

Yes- it is a Mac. I went through adobes system requirements and re- downloaded supportive software. The notice seems to happen near the end of the down load with the messages above. I'll look into your suggestion. Thank you- appreciated.

Cannot write email body in OWA with Exchange 2013 SP1 CU6

Hi,
I have a problem with Exchange 2013 SP1 with CU6.
All of OWA user cannot write in the body of email. They can write the Object and the recipient but they cannot select body and write the body message. We have try with multiple Web brother and desactivate all Add-on but the problem still there...
The only way that works is to respond to an email, and in that case, it's working, we can write normally in the body of email.
Have you an idea ?
Thanks in advance!

Hi,
After contacting Microsoft support, we have found the solution.
The problem appear after we have recently install the patch described in this KB 2997209:
https://support.microsoft.com/kb/2997209?wa=wsignin1.0
But on 2013 Mailbox Server, Echange is not installed in the default path C:\ but on D:\
So we have to manually copy the content of folder D:\Program Files\Microsoft\Exchange Server\V15\ClientAccess\Owa\prem\15.0.995.29 in the folder 15.0.995.31 (MAKE a BACKUP of FOLDER BEFORE!)
No need to reboot, or restart IIS, it's working after that!
