Hello
We had an electrical problem on our enviroment and after the rp4440 connected to DS2120 storage the "vg01" shows an error message during mounting a filesystem.
I tried to check with fsck but without success, and I would like to know if there anything that I can do to mount, without formating and restore data back.
#fsck -F vxfs -o full -y /dev/vg01/rlvol1
log replay in progress
vxfs fsck: fsck read failure bno = 3838776, off = 0, len = 8192
full file system check required, exiting ...
Please let me know if you know anything to help me.
Thanks
Solved! Go to Solution.

Re: Full fsck problem
The read failure indicates a disk problem. You should also see errors in the output from the command: dmesg
You will should also see errors logged in the file /var/adm/syslog/syslog.log
If the lvols in vg01 are mirrored (vgdisplay -v vg01). you can replace the bad disk (identified in syslog.log). Otherwise, you'll have to replace the bad disk and rebuild vg01 and restore the lvol(s) from your backups.
One other possibility: did someone use the lvreduce command?
The read error may be caused by trying to read beyond the end of the lvol.

Re: Full fsck problem
Routine question: was the filesystem check done against a mounted filesystem (probably the rlvol1 was moutned read-only)?
A filesystem check should always be performed against an unmounted filesystem...so try first to unmount (umount) the filesystem which is experiencing the issue and repeat that exact fsck command against it once you're sure it is cleanly unmounted.

SolutionI had no luck with cleaning the filesystem.
After the server and storage went down because a power outage, the fsck failed even when I tried to boot in low maintenance mode, always returing the same message "vxfs fsck: fsck read failure bno = 3838776, off = 0, len = 8192"
I have created a new VG with a new lvol and I did a restore data from a tape drive.
Sadly I lost about 6 hours in this restore procedure, but thanks to all for your answers, because I tried your sugestions before anything else.
Thanks.

Re: Full fsck problem
Repair Root File System
Enter the boot menu and choose Advanced Options.
Select the Recovery mode and then тАЬfsckтАЭ.
When prompted to remount the root file system choose тАЬYesтАЭ.
Once done, resume the normal boot.
