Extending an LVM Logical Volume
As a followup to my AoE storage server posts (Part 1, Part 2), I recently needed to extend an LVM logical volume from 1TB to 1.3TB. As per the LVM howto, I followed these steps:
On the "client" (the server that had mounted the AoE share):
umount /backups
On the storage server:
vblade-persist stop 0 1
lvextend -L1331GB /dev/data1/backups
e2fsck -f /dev/data1/backups
resize2fs /dev/data1/backups
vblade-persist start 0 1
On the "client":
aoe-stat
mount /dev/etherd/e0.1 /backups
HighPoint RocketRaid 3540 fails under heavy I/O
As I previously mentioned in my posts about using AoE on Debian for a storage server, I chose to use a HighPoint RocketRaid 3540 RAID controller for RAID; however, I have been having problems where it fails under heavy I/O. After contacting HighPoint's support department, they acknowledged that there is a known defect related to failure under heavy I/O on all RocketRaid 3540 controllers with serial numbers beginning in "08", and agreed to RMA my card.
UPDATE: I RMA'd the card and HighPoint replaced it with a working version, although I'm not sure what the difference is because the replacement also has a serial number beginning in "08". Perhaps a firmware/BIOS update?
