Hardware Raid Expansion and LVM

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



All,

I am looking for a little help on finding out the best way to do this. I had a 4 disk 1.4TB RAID 5 array, and extended that to an 8 disk 3.18TB array, on a 64 bit system.The Raid card handled the migration of the disks well, and everything on that side is up and running as it should. Problem is I don't know how to extend LVM to a larger size, without doing the whole adding of physical drives, and so forth, and the pv display doesn't show more than the 1.4TB that I started with. Most documentation details software RAID procedures that don't really work with this. I figure I am doing something(lots of things) wrong.

Commands I have used:

Thu Oct 09-13:10:36-root@haruhi:~> pvs -o +dev_size
 PV         VG         Fmt  Attr PSize PFree   DevSize
 /dev/sda2  VolGroup00 lvm2 a-   9.78G  64.00M   9.81G
 /dev/sdb1  VolGroup00 lvm2 a-   1.35T 576.00M   1.35T

This error is after I resized the pv back to its original size:
Thu Oct 09-13:11:32-root@haruhi:~> lvresize -d -L 3.18T /dev/VolGroup00/LogVol00
 Rounding up size to full physical extent 3.18 TB
 Extending logical volume LogVol00 to 3.18 TB
 Insufficient free space: 59572 extents needed, but only 20 available

Before that I was seeing:
device-mapper: reload ioctl failed: Invalid argument
Failed to suspend lv1


Kernel output
