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?
