Faulty system drive

I use a Compact Flash card as the system drive in my server. The purpose of this is to keep it cool and to keep the noise down. It doesn’t have any fans or moving parts at all, so it’s completely silent. A blue led is the only thing telling it’s powered on. Today I received reports in the mail about read errors on that drive:

Jan 29 12:20:17 warhammer kernel: [2067530.622415] sd 0:0:0:0: [sda] Unhandled sense code
Jan 29 12:20:17 warhammer kernel: [2067530.622422] sd 0:0:0:0: [sda] Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE
Jan 29 12:20:17 warhammer kernel: [2067530.622434] sd 0:0:0:0: [sda] Sense Key : Medium Error [current] [descriptor]

Jan 29 12:20:17 warhammer kernel: [2067530.622514] sd 0:0:0:0: [sda] CDB: Read(10): 28 00 00 c4 ce 28 00 00 08 00

 

Probably nothing more to do than exchanging the CF card to another one. I’ll use Clonezilla Live to migrate the system. I’ll probably upgrade to Oneiric Ocelot while I’m at it too…

Syslogging in Natty Narwhal

Having recently moved up to Kubuntu 11.04 Natty Narwhal, I noticed early on that the log file /var/log/messages was missing in the new install. Seeing this a peculiar but not investigating further to why it was missing, I finally did caved in and did some quick googling on the matter.

It turns out the developers felt it was redundant to save the same data in both /var/log/syslog and /var/log/messages. I have previously felt that they are similar but they are not identical, as /var/log/messages holds more information than what is found in /var/log/syslog.
