Hi,
I am little puzzled. I looked through the mailing list archive and some
other sources but doesn't seem like anything anyone encountered.
I have two systems with attached HP SAN. I'm using SLES 10.1 with
multipath-tools. When trying to mount OCFS2 device I get this:
SERVER:/ # mount.ocfs2 /dev/mapper/mpath0 /mnt/temp/
mount.ocfs2: Invalid argument while mounting /dev/mapper/mpath0 on
/mnt/temp/. Check 'dmesg' for more information on this error.
So when I check dmesg I get:
(8854,0):ocfs2_initialize_super:1418 ERROR: couldn't mount because of
unsupported optional features (10).
(8854,0):ocfs2_fill_super:566 ERROR: status = -22
ocfs2: Unmounting device (253,8) on (node 255)
When looking at the command with strace I see this line:
mount("/dev/mapper/mpath0", "/mnt/temp/", "ocfs2", 0, "heartbeat=local") =
-1 EINVAL (Invalid argument)
What does this mean? The error is rather cryptic. Thanks.
