(1) Watching the device for I/O errors works in the single-disk case. This is fairly obvious. (2) Pulling one of the disks in a software RAID/LVM set will not generate I/O errors at the RAID/LVM level, so this is covered. (3) Pulling all disks in a software RAID/LVM set has not been tested yet. The assumption is that it will generate I/O errors, but this is not necessarily the case. [TODO] (4) I/O error checking will work fine in any hardware or host-RAID controller (without additional software RAID/LVM), given that they appear as regular SCSI disks to the host. A better implementation of this would be similar to our disk monitoring application which we've crafted for RHEL4 to supplant the previous quorum-disk monitoring we did. |
