Hi list. I recently completed a migration of my home fileserver form LVM on two ide disks to LVM on RAID-5 with 4 ide disks. I attempted to extend one of the logical volumes, but it failed with this message:
[EMAIL PROTECTED]:~$ sudo lvextend -L+25G /dev/mommadisk/video
Password:
Using stripesize of last segment 4.00 KB
Extending logical volume video to 200.00 GB
Not enough PVs with free space available for parallel allocation.
Consider --alloc anywhere if desperate.
hmmm... I know there is enough room on the raid disk /dev/md2

with 173 GB free, it should be no problem to extend the lv. I was able
to successfully extend one of the other lv's, but not this one. There
must be something I'm not understanding here.
okay, one thing I discovered while setting up this email is that some
of my raid disks are degraded (probably due to a configuration problem
on my end), but would that cause that problem?? currently in the midst
of fixing that up. only some 450minutes to go... weeee.
a bit more info below...
thanks
