Hi,
I've setup two 30GB IDE drives for RAID 1 mirroring.
It works during normal conditions, but I'd like to test some failure
modes.
I tried disconnecting the power to one of the drives. I got a bunch of
consoles messages -- access to the filesystems on the mirror blocked. Once
I powered up the second drive again, accesses completed. Here's the logs:
Oct 28 05:21:40 leaf /kernel: ata1-master: no status, reselecting device
Oct 28 05:21:40 leaf last message repeated 757 times
Oct 28 05:21:40 leaf /kernel: ata1-master: timeout waiting to give
command=c8 s=ff e=ff
Oct 28 05:21:40 leaf /kernel: ad2: error executing command - resetting
Oct 28 05:21:40 leaf /kernel: ata1: resetting devices .. done
Oct 28 05:21:50 leaf /kernel: ad2: READ command timeout tag=0 serv=0 -
resetting
Oct 28 05:21:50 leaf /kernel: ata1: resetting devices .. done
So.. is vinum capable of continuing to operate when a drive fails, or will
the system always die block on accesses and require a reboot?
I'm hoping the system can continue to operate during a failure, even if
I'm not around to reboot the system. I'm running 4.1-STABLE.
Perhaps if the OS could just be made to not spaz out when a drive fails?
Thanks,
