Frank, you may want to go to the Virtual Disk and do a "check consistency". This compares the data from one physical disk to the other (raid1) and corrects any bad blocks.

Hi All, One of our 3-year old PE2950 servers recently throw Mysql table read errors frequently, especially in this month. We noticed the 'medium error' shown in the log exported from OMSA as following started from 07/23/10, 07/23/10 18:41:16: DEV_REC:Medium Error DevId[3] Tgt 3 retires=0 07/23/10 18:41:16: EVT#04531-07/23/10 18:41:16: 110=Corrected medium error during recovery on PD 03(e1/s3) at 17a7753b 09/17/10 4:38:54: DEV_REC:Medium Error DevId[3] Tgt 3 retires=0 09/19/10 4:39:27: DEV_REC:Medium Error DevId[3] Tgt 3 retires=0 ... 10/17/10 10:52:10: EVT#05193-10/17/10 10:52:10: 110=Corrected medium error during recovery on PD 03(e1/s3) at 17b2e07b 10/17/10 14:53:34: DEV_REC:Medium Error DevId[3] Tgt 3 retires=0 10/17/10 15:43:01: DEV_REC:Medium Error DevId[3] Tgt 3 retires=0 10/17/10 17:41:32: DEV_REC:Medium Error DevId[3] Tgt 3 retires=0 10/17/10 18:02:01: DEV_REC:Medium Error DevId[3] Tgt 3 retires=0 10/17/10 19:12:49: DEV_REC:Medium Error DevId[3] Tgt 3 retires=0 10/17/10 19:12:50: EVT#05200-10/17/10 19:12:50: 110=Corrected medium error during recovery on PD 03(e1/s3) at 17a73c51 10/17/10 19:42:59: DEV_REC:Medium Error DevId[3] Tgt 3 retires=0 10/17/10 19:43:00: EVT#05202-10/17/10 19:43:00: 110=Corrected medium error during recovery on PD 03(e1/s3) at 17a743f6 And the first Mysql table error was reported on 07/24/10 according to log, 100724 9:22:13 [ERROR] /usr/libexec/mysqld: Incorrect key file for table './discuz/cdb_threads.MYI'; try to repair it 100724 9:22:13 [ERROR] Got error 126 when reading table './discuz/cdb_threads' ... 101018 16:36:35 [ERROR] Got error 127 when reading table './discuz/cdb_promptmsgs' So far, we're still doing other integrity test on the DB and don't know if the two are related. The VD status in OMSA is ready (green check) though. Should I worry about this and replace the PD 03(e1/s3) disk? Any suggestion? Thanks!
