Greetings,
I recently got an HP surestore 215 external Ultrium 1 drive. I
set it up in Bacula and it is working great. The only problem is that I am
only getting about 2mb/s on backups. Here is the setup I am using:
Tape drive is connected to a LSI megaraid 320-2 raid card
Tyan LE-T motherboard
2 x 1.4ghz Intel Tualatin CPUs
2.5gb of ram
2 x 36gb Ultra-320 15000rpm scsi hard drives in raid 1
CentOS 4.4
Bacula 2.0.3-1
Tape drive is hooked to a different scsi channel than the drives.
I have run the btape test command and it passes without any problems. Should
I try using a regular SCSI card instead of the megaraid card. I tried
hooking the tape drive up to a Sun Netra T1 105 running FreeBSD 6.2 sparc64.
I was getting around 8mb/s execpt the storage daemon would hang any time I
tried restoring. I also hooked the drive up to my HP C3000 HP-UX workstation
and ran the HP LTT diagnostics on the drive. It passed all tests and was
showing 15mb/s on writes. Any help would be greatly appreciated. Here is
the output of the btape fill command:
08-Apr 16:31 btape: Fatal Error at dev.c:1670 because:
