advfs domain panic

[james_lee]

I have got ADVFS domain panic, and I could not access to my /home directory. I had tied to fix with verify, fixfdmn, and salvage commands, but those didnot work.
I need to recover data in that directory since I don't have backup.
The followings are error messages I got:

AdvFS Domain Panic; Domain home_domain Id 0x3b8f191f.0003f52d
An AdvFS domain panic has occurred due to either a metadata write error or an internal inconsistency. This domain
is being rendered inaccessible.
Please refer to guidelines in AdvFS Guide to File System Administration regarding what steps to take to recover th
is domain.
Domain panic appears to be due to a hardware problem

With fixfdmn, I got this messages:
# ./fixfdmn home_domain
fixfdmn: Can't get size for volume '/dev/disk/dsk1c'.
fixfdmn: Error obtaining volume information.

Please let me know if you have any clues to recover my data.
Thanks in advance.

With that kind of error, I would think salvage would be a better bet - you said it didn't work though. What does the output of 'salvage' look like?

[james_lee]

The followings are the output from 'salvage' command:

# ./salvage home_domain
salvage: Domain to be recovered 'home_domain'
salvage: Volume(s) to be used '/dev/disk/dsk1c'
salvage: Files will be restored to '/sbin/advfs'
salvage: Logfile will be placed in '/sbin/advfs/salvage.log'
salvage: open() failed for Device '/dev/disk/dsk1c'
salvage: No such device or address

"Domain panic appears to be due to a hardware problem

This is the clue. Did you check the binary error log? I don't think AdvFS can do much if the disk is inaccessible. Time to check out the backup.

Yes, that clearly indicates a hardware error on dsk1. Did you check the binary error log? Can you access the disk in any other way? For example, does 'disklabel -r dsk1' work?

Yes, I have checked binary.errlog, but I don't undertand what the error log means.
It keep saying that

Also, I tried disklabel, but it doesnot work.
I cannot access to "dsk1c".
Thanks.

It sounds like the disk has failed.

[Venkatesh BL]

Yes, please recreate the domain/filesets on a new disk(s) and retrieve data from backup.
