Why am I experiencing I/O error in my /var/log/messages file, and what does it mean?


You may see errors similar to the ones below in your /var/log/messages:
kernel: end_request: I/O error, dev sdb, sector 970590828
kernel: scsi0 (1:0): rejecting I/O to offline device
kernel: Buffer I/O error on device sdb8, logical block 2014311
kernel: lost page write due to I/O error on sdb8
kernel: I/O error in filesystem ("sdb7") meta-data dev sdb7 block 0x1e980dcc ("xlog_iodone") error 5 buf count 2048
kernel: Filesystem "sdb7": Log I/O Error Detected. Shutting down filesystem: sdb7


- The firmware was not updated on Hard drives and/or Perc raid controller - If firmware was applied, It is possible the hardware has failed  - Bad SCSI cable - File system corrupted

- Corruption on the disk has caused data loss causing SIM services to fail to start
