Repair GPT partition

[gac]

Hi
I have setup a GPT partition 4TByte with #parted it works fine but after a powerfail it was impossible to repair the file system with fsck. My question is : how to repair a GPT ext2 filesystem with fsck ? parted ?
Thank you very much
Gilles

Without more details, it's impossible to say what's wrong, much less how to fix it. First, though, you should understand that the partition table type (GPT, MBR, APM, etc.) is independent of the filesystem type (ext2fs, ReiserFS, FAT, etc.). If you have no entry for the partition device file (/dev/sda2 or whatever), then the problem is most likely in the GPT data structures. If you can "see" the filesystem but not repair it, then the problem is almost certainly at the filesystem level and not in the partition table data structures. Thus, you should begin by posting that information -- do you have device entries for your partitions? You should also post the output of the following commands:

parted /dev/sda print
fsck /dev/sda2

Change "/dev/sda" to your disk device and "/dev/sda2" to the partition that's giving you problems. (Obviously, you won't be able to use the fsck command if you don't have the relevant device node.)

oussena, I recommend you start your own thread; your problem may have a very different cause and solution to gac's problem, and trying to solve two problems in one thread generally creates confusion.

Since gac posted over 6 years ago, I sure hope his problem is fixed by now

I'll leave this one going, even though it could be a totally different problem, and focus on oussena's problem instead of gac's.

I will say this, though..

Oussena.. in the future, you will probably get much better responses if you start a new thread instead of resurrecting a 6 year old one. I do think it's great you used the search function before posting, though

Than you very much for your quick answer. In fact i found the problem, someone have overwritten the file system to change it vfat, hence all the superblck i used with e2fsck did not work..
