======Other Days======

======March 13th, 2015======
=====data1 drive replacement=====
On Tuesday, mdadm started reporting a failure in one of the drives in data1 (sdd)... I ordered a replacement, and finally got around to replacing it on Friday.

The hardware side of the equation went as expected and without incident. I then proceeded to spend far too much time convincing a broken grub to reinstall (ended up netbooting finnix, chrooting in).

I re-added the drive to the md volume (after rebuilding the initrd and rebooting):

<cli>
data1:~# mdadm --add /dev/md0 /dev/sdd
</cli>

and left it rebuilding the RAID.

======March 14th, 2015======
=====drbd fun with data1=====
With the md raid volume rebuilt, I set about getting the two peers once again talking... as has been the case in the past, this has proven non-trivial... the apparent working recipe:

<cli>
data1:~# drbdadm disconnect lair_data
data1:~# drbdadm connect --discard-my-data lair_data
</cli>

I had also issued an **outdate** to data1's data (which didn't seem to make a difference, or maybe it did, and "discard-my-data" doesn't imply ALL data, but merely some sort of small difference in unsynced data)... at any rate... they are once again talking.
