Hi.
I am testing adding device to raid5 and I have some questiones.
How can I intrepret this line from dmesg (after growing):
ioctl32(mdadm:3762): Unknown cmd fd(3) cmd(90000915){10} arg(ffffa758) on /dev/md0
What this means:
Filesystem "md0": Disabling barriers, not supported by the underlying device
And i have another question, not connected directly to raid.
When I run "xfs_growfs" I get this errors:
xfs_growfs: XFS_IOC_FSGROWFSDATA xfsctl failed: Invalid argument
xfs_growfs: XFS_IOC_FSGEOMETRY xfsctl failed: Invalid argument
And in dmesg:
ioctl32(xfs_growfs:4024): Unknown cmd fd(3) cmd(806c5864){00} arg(ffffcb20) on /mnt/test
Thanks for help.
(custom kernel 2.6.17-rc2, mdadm 2.4.1, xfs_growfs 2.7.16, processor Athlon64 (x86_64) )
Thanks!
MM.
