[Linux-cluster] GFS2 'No space left on device' while df reports 1gb is free

[Vladislav Bogdanov]

Hi,

I've got weird state on GFS2 (activated only on one node from the very 
beginning, but with dlm locking), when I'm unable to write with 'No 
space left on device' error, but df -m reports:
/dev/mapper/vg_shared-lv_shared 570875 569622 1254 100% /storage/staging

Umount/mount doesn't help, umount/fsck/rmmod/mount also does nothing.

That is centos6 with 2.6.32-504.30.3.el6.x86_64 kernel.

What could be the reason for such desync?
Is there a way to fix that?

Any help is appreciated,

thank you,
Vladislav
