This just happened on my server:
Nov 22 03:21:11 sockeye kernel: ad0: TIMEOUT - WRITE_DMA retrying (2 retries
left) LBA=28892960
Nov 22 03:21:11 sockeye kernel: ad0: WARNING - removed from configuration

ad0[WRITE(offset=14793195520, length=2048)]
Now the ad0 Master drive no longer exists:
-su-2.05b$ sudo atacontrol list
ATA channel 0:
Master: no device present
Slave: acd0 <SONY CD-ROM CDU5212/5YS1> ATA/ATAPI revision 5
ATA channel 1:
Master: ad2 <WDC WD800JB-00JJA0/05.01C05> ATA/ATAPI revision 6
Slave: ad3 <WDC WD400BB-75FRA0/77.07W77> ATA/ATAPI revision 6
What is the relationship between atacontrol and gmirror?
Why was the device removed completely?
Can I simply do this? (want to be sure as this box is remote)
gmirror forget data
atacontrol attach ata0
gmirror insert data ad0
