| |
From: Andreas Behnert <abehn@gmx.net>
Yesterday I installed an external RAID system, machine was running kernel 2.2.20 and everything worked ok: ~snip~ SCSI device sdb: hdwr sector= 512 bytes. Sectors=1278558208 [624296 MB] [624.3 GB] ~snip~
Then I compiled 2.4.21-pre7: ~snip~ SCSI device sdb: 1278558208 512-byte hdwr sectors (-444889 MB) ~snip~
The system *seems* to work ok but I don't know if it really *does* - I didn't want to experiment very much because the RAID array contains sensitive data
Yes, this is a frequent complaint. Nothing is wrong, only the message. It is fixed by the patch below.
