Hello.
3.10.40 kernel and creating files causes "No space left on device". After
deleting some files I can create new files again until the problem happens
again.
Any ideas what is going on and, what is more important, how to fix the
problem?
# df -h

# df -i

imaxpct=25% but current inodes take only about 2GB, much less that 25% of
600G, so that shouldn't be problem
/dev/mapper/vgsys-home /home xfs
rw,nosuid,nodev,relatime,attr2,inode64,usrquota,prjquota 0 0
so inode64 is not a problem

so quota is not a problem, too.

unfortunately no idea how to interpret this. Man page isn't helpful.
