After procrastinating for half a year, I've decided it's too scary to
just swap out the old SSDs with the new, bigger ones.
So I've bought a new RAID controller and will be inserting that, and all
the SSDs, into a machine that has sufficient disk slots for that, and
copy over the spool.
It'll be more controlled, and downtime should be like half an hour
instead of a day.
The only machine that has sufficient number of slots is
plane.gmane.org. It's currently being used as the MTA and as an
experimental search engine thing, I think.
It currently has the following disks:
/dev/sda7 2.0G 625M 1.3G 33% /tmp
/dev/sda8 7.9G 2.4G 5.1G 33% /var
/dev/sda9 12G 2.9G 8.4G 26% /usr
/dev/sda10 30G 4.1G 25G 15% /opt
/dev/sdb1 1.4T 747G 560G 58% /mirror
/dev/sdc1 1.4T 269G 1.1T 21% /index
/dev/sdd1 1.4T 1.1T 276G 79% /ispool
So four slots taken, and the mirror disks are too small. So I'm going
to rip out those three 1.5TB disks and put in the five 1TB SSDs, and
also two new 4TB disks that can be used for search indexing and stuff.
(The machine has room for 8 disks.)
