I've been encountering some problems with my system since upgrading
Geek.NET to 2.2.15. Since the upgrade, I have not been able to make a
successful backup of my system to my Sonny DDS-3 tape drive. Tonight, I
ran a manual backup to watch it and all hell broke lose.
First, some stats:
System: Dual PII-400 w/ 256 MB
ASUS P2B-DS Motherboard with intergrated
Adaptec 7980 Controller
Drives: 1 Quantim 9GB Ultra 2
1 CMD 5440 External RAID Controller w/
3x9gb IBM UW SCSI (RAID 5)
1 Sony DDS-3 Tape Drive
1 NEC SCSI CDRom
Network: 1 Intel EtherExpress Pro 100
Video: Nothin special, in console mode anyways
---Symptoms and Errors:
When I use BRU to do a full system backup, I've not been able to get a completed backup since upgrading to 2.2.15. However, I've not assumed a kernel problem due to the fact that I've had some niggling power issues in the last week (UPS install tomorrow!) and I've always had to re-insert the tape if the machine reboots. Having reboots have also meant about a half-dozen FSCKs, but they have always completed without probem.
Tonight, I popped in a brand new tape and ran a manual backup. I then had the following pass by the console:
... May 13 00:01:01 geek kernel: scsi0: MEDIUM ERROR on channel 0, id 1, lun 0, CDB: Read (10) 00 01 62 83 c7 00 00 08 00 May 13 00:01:01 geek kernel: Info fld=0x16283c8, Current sd08:11: sense key Medium Error May 13 00:01:01 geek kernel: Additional sense indicates Unrecovered read error - recommend rewrite the data May 13 00:01:01 geek kernel: scsidisk I/O error: dev 08:11, sector 23233416 May 13 00:01:04 geek kernel: scsi0: MEDIUM ERROR on channel 0, id 1, lun 0, CDB: Read (10) 00 01 62 83 c7 00 00 08 00 May 13 00:01:04 geek kernel: Info fld=0x16283c8, Current sd08:11: sense key Medium Error May 13 00:01:04 geek kernel: Additional sense indicates Unrecovered read error - recommend rewrite the data May 13 00:01:04 geek kernel: scsidisk I/O error: dev 08:11, sector 23233416 ...
After a minute, the error ended and the machine unlocked and resume normal operations and the backup continued.
A short time later, I got another error that unfortunately didn't log and I didn't get the specifics. It was some kind of an "unable to read" followed by an "unable to write" to both the single hard drive (/dev/sda) and the RAID array (/dev/sdb). This time the machine totally locked and I was forced to power cycle. I don't know if I could have left it for a while and had the machine recover operation. I was more in panic mode at that point ;-).
After reboot, the system did it's fsck just fine. I looked at uk.kernel.org for the 2.2.15 release notes and saw updates had been made to the 7xxx drivers and it seemed to fit the fact my in-ability to back up began with my upgrade to 2.2.15.
Tomorrow I have a planned outtage to install the UPS and other things. At that time, I'm going to try another manual backup using the 2.2.14 kernel and see if I'm successful. For the time being I've downgraded back to 2.2.14 just to ease my mind over night.
Any thoughts here? I'm including a copy of dmesg, as reported by 2.2.14, below.
Thanks much
