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.
