8 sdb6 is part of a mirror, yes. No loss of data so far, no failed arrays,
9 nothing.
10
11 Just that smartd-test failing last night and now I have to act.
12
13 The 3 arrays are OK and also fully on tape, that's not the problem.
14
15 My concern is about /dev/sdb5, which is the one and only PV inside the
16 lvm2-VG VG01 (oh my, I fear Volker right now telling me about that
17 LVM-stuff ;-) ). And VG01 hosts a few LVs, most of them easy to restore
18 or rebuild, one of them containing around 700GBs of mythtv-recordings.
19
20 Most of those are also on tape, but not all of them (because I run out
21 of space with tapes etc). Nothing really important, sure, it's "just
22 TV", but nice-to-have anyway.
23
24 So I am moving stuff from that LV to another new RAID-array, just to
25 save that data before sdb maybe crashes completely.
26
27 In general I am rebuilding that whole box lately, adding drives etc. but
28 I am not yet where I want to get because I hit one obstacle after the
29 other. I suspect the power-supply to be faulty ( I also get
30 chksum-errors in a zfs-fuse-pool, before and after using new disks ...
31 so ...)
32
33 RAM is good, at least as far memtest86+ is able to tell.
34
35 *sigh*

37 Thanks, Stefan
