Subject: How to recover this RAID5?
Date: Sun, 08 Jun 2003 06:31:30 -0600 [thread overview]
Message-ID: <5.1.1.6.2.20030608061637.03bb34e0@mail.harddata.com> (raw)
Hi there.
I am a bit stumped on this one, and hope somebody can suggest a way to
recover it.
The user has no backup, and hopes to recover data from this array.
Assistance would be deeply appreciated.
System has 4 IDE disks on a 3Ware 4 port.
RAID5.
One of the disks apparently went offline without the user noticing.
Now the array is in a read-only state.
Probable cause is that these are WD 1800GB drives, and they have not had
the WD patch applied, so probably drives started going to "sleep".
I provide some (hopefully) useful information:
In mdadm --examine I see that somehow the devices 1,2,3, have now been
renamed to devices 4,5,6
And that 2 devices have become designated as spares.
This really puzzles me.
The data from mdadm --examine /dev/sd[abcd]1:
