Hi there,
I have a 2 RAID 1 mirrors brake in front of my eyes, pretty much. they
were based on ad4 and ad8 (SATA drives, the board has 2 SATA
controllers). It seems ad4 either died or the primary controller did. I
was writing several GBs of data to the 'mirror_data' device and...poof :-/
Can anyone tell from the info below whether it's the disk that died, or
that controller? anyone seen anything like this before? (sorry, new to
gmirror). Any tests that can be suggested (other than surface test,
which I'll have to do after the weekend).
6.0-BETA3 (dual) amd64, SMP kernel, on a Tyan GT24b2891
http://tyan.com/products/html/gt24b2891_spec.html ).
ad4: 238475MB <WDC WD2500JS-00MHB0 02.01C03> at ata2-master SATA150
