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