[XFS] filesystem corruption

[skai]

Hi everyone,
I'm currently (and for a few weeks) having a problem with a 2T usb drive connected to a raspberry Pi model B,
running Arch, up to date (last update hours ago).

Here's what happens.
The filesystem is declared "corrupted".
(please run xfs repair, see log below)

I umount, run xfs_repair, mount : problem persists.

There is for instance a directory I can not access : I see the name, can cd in it, but a "ls" will produce an error message.
$this->bbcode_second_pass_code('', '
ls: reading directory /mnt/dlna/Photos/2012_08: Structure needs cleaning
')

Worst : I umount, plug the disk to a 86_64 laptop, I mount : no corruption detected, directory available !

So : I did cp -rp from the given directory, *delete* the original directory,
unmount, mount back to the ARM.

And guess what : the faulty directory appears again ! (and "coruption" message also)

(and once again : xfs_repair does'nt solve anything)

I have absolutely no clue as hat I should do, aside from changing filesystem

Any help will be welcome !

Here comes the log :

And here's what I'm running :
$this->bbcode_second_pass_code('', '

')


Thanks a lot !

Google around. Something must have changed recently upstream. I personally don't use xfs, but this is not the first time i'm reading a report about this.

From what I found... the problem is quite old.
(I've seen posts several years old).

Anyway, I wonder if it's not related to a memory capacity problem.
(xfs_repair may fail on RPi due to memory shortage).

I'm going to use ext4 instead.

Anyway... on usb2, the IO performances issues won't come from the filesystem

[moonman]

To be honest i never understood why people use xfs on these devices.
