Re: SLES, not large enough to join array

 Hi.

I have a setup with SLES 10 SP2 installed in 1 DELL PowerEdge 2950 attached
to 5 DELL MD1000 SAS storages (5 TB each).

I used mdadm to make a single RAID unit of my storages. I'm using RAID 5 to
prevent data loss if one of the storages fail.

I had a storage fail. I removed the faulty storage (mdadm /dev/md0 -r
/dev/sdb1) and restarted the system to replace this storage with a good one.


The new storage is an exact copy of the faulty one (including internal
HD's).

When I tried to add the new storage to my degraded array ( mdadm /dev/md0 -a
/dev/sdX1), I get the following message: /dev/sdX: not large enough to join
array.

I used the same steps in another site (with the same storages, but with only
500 GB each) and it worked all right.

Any suggestions?

Yes. Upgrade :-)

This looks like the bug that was fixed in SLES10-SP2 by an update on
May 9th this year.

The relevant bugzilla is
  https://bugzilla.novell.com/show_bug.cgi?id=368704

There is a patch linked in there.
If you cannot find an upgrade, you could just compile your own mdadm
from the latest source.
