XFS "no space left" problem

[wildcat <wildcat@espix.org>]

Hi dear list,


I recently migrated a 1.3Tbyte partition from reiserfs to XFS.
As the 1.3Tb partition was full, my idea was to shrink reiserfs
partition of 100Gig at a time, and then grow the XFS one.

This has been working since 1.1To for XFS partition. Now I'm in the
following situation:


/dev/mapper/crypt-data
                      1.2T  1.1T  134G  89% /jail2

dunno jail2 # touch a
dunno jail2 # touch b 
touch: cannot touch `b': No space left on device
dunno jail2 # 


>From there if I delete 'a', I could create a file of any size. but then
will be running
again into the "no space left".

>From here, some people told me of an inodes problem, that I checked
first:
/dev/mapper/crypt-data
                     561850144  158335 561691809    1% /jail2

is outputing from df -i.

umount/remount of the partition doesn't change anything. 


here are some information about the filesystem details:

I can't think of a Fix solution from here and I'm stuck.

As this box is in production and remotely managed; Go to the
place, take the hard drives and backup/restore is not a solution.

Any help/comment/fix/idea would be very appreciated.
Any additionnal information you need could be asked :)


TIA,
Best regards,
