There comes a time when you just have to throw in the towel and kick yourself for not creating regular backups. This has nothing to do with where a drive is made, but rather how you treat the system itself. If you know that there are power issues, one should take steps to ensure their data is protected. If not with an UPS, then ensure you're doing backups on a regular basis to ensure your data is safe.

Power failure is murder on hardware. While you may squeak by on multiple power outages, there will come a time when the law of averages will catch up and bite you in the backside. If the repair functions aren't working, your only recourse is to take the drive to a professional company that specializes in data retrieval. They  may or may not be able to get your data back. Of course, the price of a recovery isn't cheap. You have to make a decision as to whether the data is that important to spend that kind of money.

I do not know how to fix the problem. What I have found
after a little research is that this is a known kernel problem.

Here:

May give you some ideas on a fix. Like marking and moving the inode. Hopefully you helps.

but current issue of "can't read superblock" came once i deleted one big file in that partition, as i planned to backup all data to another disk afterwards.but the issue suddenly came out, yesterday the power is normal, also ups is on, no porwer surge or whatsoever,........If I hadn't deleted that big file(vl64-rc2.iso)i would have backed up all data already, no data loss.
Please current issue  nothing to do with power surge, it's another issue, it must have some fix commands there.Please help!

how about upgrading xfs_repair/xfsprogs to latest version? as current version on VL repo is too old.

http://oss.sgi.com/archives/xfs/2010-05/msg00131.html
would any developer upgrade it to the latest version and upload to VL test repo?

[vincent2]

anybody can give the commands to fix?
anybody can give the commands to fix?

[vincent2]

still expect a fix command to backup the data on xfs /home partition.
nobody 's willing to, all of you  gets sacked and unemployed without social welfare cheques from authorities?

Dude, will you please just learn your lesson and do your research on filesystems and choose a better FS?

Bumping the thread will do nothing here.
