Dear list, I get the following errors on my CentOS 4.5/Dell/Xeon Cluster with Infortrend/QLogic fiber channel SAN: Sep 17 11:24:21 dtm kernel: Buffer I/O error on device diapered_dm-2, logical block 128340454 Sep 17 11:24:38 dtm kernel: Buffer I/O error on device diapered_dm-2, logical block 128340455 Sep 17 11:24:56 dtm kernel: Buffer I/O error on device diapered_dm-2, logical block 128340456 Sep 17 11:25:14 dtm kernel: Buffer I/O error on device diapered_dm-2, logical block 128340457 Sep 17 11:25:32 dtm kernel: Buffer I/O error on device diapered_dm-2, logical block 128340458 Sep 17 11:25:49 dtm kernel: Buffer I/O error on device diapered_dm-2, logical block 128340459 Sep 17 11:26:07 dtm kernel: Buffer I/O error on device diapered_dm-2, logical block 128340460 Sep 17 11:26:25 dtm kernel: Buffer I/O error on device diapered_dm-2, logical block 128340461 Sep 17 11:26:42 dtm kernel: Buffer I/O error on device diapered_dm-2, logical block 128340462 Sep 17 11:27:39 dtm clurgmgrd: [4713]: <err> clusterfs:gfs-dtm-home: Mount point is not accessible! Then the filesystem is not mountable on this node anymore (it's set up using rgmanager to mount the gfs). On the other nodes, there are no problems. How can I debug this if it's dependant on the hardware or something is wrong in the filesystem?
