it is running in a vmware esx 3.0.1 environment with a Sun STK 6140
storage array.

During a disk change the following error is logged by the kernel:

sdc: Current: sense key: Recovered Error
<<vendor>> ASC=0xe0 ASCQ=0x6ASC=0xe0 ASCQ=0x6
EXT3-fs error (device sdc1): ext3_free_blocks_sb: bit already
cleared for block 75569857
Remounting filesystem read-only

I have to reboot and fsck the partition.

Recovered Errors sounds like - there was an error, but the storage
recovered it, by itself - so wy the ext3 failure occured?

The same issue happend on a ubuntu 6.06 lts ( Kernel 2.6.16 ).

All debian sarge with kernel 2.4.27 survived the scsi error.

Is there a setting, to tell the kernel to retry the read or write
operation?

Regards,

Konrad
