While moving my fileserver to a new rack I inadvertently connected the cables of the disk arrays to the wrong SAS ports. When I rebooted the disksgot assigned new UUIDs but the old ones were not removed, so the volume group will not activate and mount.
My question is how do I remove the old metadata?
System details:
CentOS 6.2
Dell Poweredge r210
LSI MegaRAID 9280
2 Sans digital disk enclosures
Here is the LVM info

As you can see there are 2 PVs that are an unknown device and that seems to be causing problems.
How should I proceed?

Hi,
I have extended the logical drive on my SMART ARRAY on a BL460 C class blade from 72G to 300G (disk upgrade RAID0+1).
It went fine and the new larger disks have now sync'ed up.

Hi,
I'm new to HP-UX.

Hi All,
I created an lvm filesystem with a name with dash in the middle, like xxx-yyy (note, that it's only one dash).
I was able to create it smoothly with this instructions.
lvcreate -L 1G uservg -n xxx-yyy
ls /dev/uservg/xxx-yyy (check)
mkfs.ext3 /dev/uservg/xxx-yyy

Hi guys,
I have been Linux for quite a while yet, but am only getting into the LVM world just now, so I do want to ask a pretty basic question (I believe for someone with experience with it) I have a physical volume of /dev/sdc1 which contains a volume group call backup that contains 2 logical...

Sorry for the noob question; my experience is with Solaris.
Am I reading this right? Are these disks completely unused? Not possibly raw disks for informix or something?

Having first encountered LVM in HP-UX and now experimenting with it in Redhat and Gentoo, I am wondering, when is it actually good practice to use LVM? Obviously LVM doesn't work for boot partitions, so that question is a pretty easy answer: Not for /boot in Linux.
While trying to figure out... (1 Reply)
