[linux-lvm] vg availability during boot

[Eugene Vilensky <evilensky gmail com>]

Greetings,

I have a host that refuses to recognize my san-attached logical
volumes during boot.  When mounting from /etc/fstab, it drops out of
boot complaining that the LVs in question have an invalid superblock
and need to be fsck-ed, however because the lv is "mounted" the fsck
cannot proceed.

I commented out the entries, rebooted, and noticed that the LVs in the
VG in question are "NOT AVAILABLE."  A vgchange -a y vgname later and
everything is working perfectly.

This is my first RHEL5 san-attached host; might I have missed some
sort of 'vg persistency' settings by doing the same things I've been
doing on RHEL4?

Thanks,
