It could be a bad drive, bad san or bad Host Bus Adapter (HBA). Perhaps you should unmount the san from all the nodes, then from one node, do a simple read test of the san: 1. Check dmesg and maybe clear your dmesg buffer: dmesg -c 2. Try reading every sector of the san: dd if=/dev/sdb of=/dev/null bs=1M 3. Check your console / dmesg to see if SCSI errors are reported. You may want to try that separately on a few different nodes just in case the error was caused by a bad HBA in the node that reported the problem.
