[Ocfs2-tools-users] mkfs.ocfs2 error

[tcameron at cox.net]

Hi All,

I'm trying to set up a cluster for the first time, but getting an error when attempting to create the filesystem.  I'm running SLES10.  /dev/sdb is an iscsi disk; that layer seems to be working fine as parted and cfdisk can work with it.

cm1:~ # mkfs.ocfs2 --verbose -b 4K -C 32K -L OCFS2 /dev/sdb1
mkfs.ocfs2 1.2.3
mkfs.ocfs2: Could not write: Input/output error

As I mentioned, the virtual disk and partition seem to be fine, as this works:

cm1:~ # mkfs.ext3  /dev/sdb1
mke2fs 1.38 (30-Jun-2005)

This filesystem will be automatically checked every 35 mounts or
180 days, whichever comes first.  Use tune2fs -c or -i to override.

Any ideas what this could be, or what techniques I can use to help troubleshoto this?

TIA,

Tom
