Thread-topic: False No space left on device error
logfs2.nyc#mount
/dev/mapper/raidvol-vol1 on /u01 type xfs (rw,inode64)

logfs2.nyc#touch a
logfs2.nyc#touch b
logfs2.nyc#touch c
logfs2.nyc#touch d

Well looks like the initial test worked... What to do
what to do... QA perhaps?

I will run some tests and see if I lose any data...

Will xfs_recover work with 64 bit inodes?

even that kernel uses 32 bit inodes by default...

64-bit inodes -should- be safe on x86_64; an interesting
test would be to mount with the inode64 option & see if
you can create another inode.

Caveat, though - I can't say 64-bit inodes on x86_64 have
had much/any testing...
