Subject: raid1, cylinder, LBA and inexistent partitions
Date: Mon, 10 Jan 2005 17:51:28 +0100 [thread overview]
Message-ID: <20050110165128.GA28377@bluff> (raw)
Hi all,
A customer of mine have a sistem w/ very simple raid1
configuration. Yesterday, the UPS has been manually switched off by
mistake. The system woke up in degraded mode but in a strange way: one of
the discs does not seem to be partitioned, according to devfs. So that I
cannot use mdadm to assemble the partition.
More: fdisk, cfdisk and /proc do not agree on the unmber of
cylinders. Only cfdisk sees it as remapped in LBA mode (9964) the others
see 158816: does that mean anything usefull? Should I change the disk (3
weeks) or can I try something different?
Thanks in advance

PS: not to mention that the disk on bus1 was partitioned exactly as the
other one...
