Greetings,
I ran into serious trouble creating a RAID-5 with the latest 3.0.5 betas and
release candidates. The symptom is that directly after the creation of the
array, there is a 'removed' device. The output of ``mdadm -D'' is like this:
Number Major Minor RaidDevice State
0 8 5 0 active sync /dev/sda5
1 8 21 1 active sync /dev/sdb5
2 0 0 2 removed
3 8 37 3 active sync /dev/sdc5
Furthermore, the array does not function properly, e.g., it misbehaves when a
redundant drive is disconnected.
I found no prior documentation of such a problem, and I did not get any
responses to my posts on Usenet about it. Left to trial-and-error, I found
out that this problem does not exist with the latest version of mdadm, which
is version 2.6. Trustix uses 2.5.
I hence suggest updating mdadm to version 2.6.
Kind regards,
Lasse
