Unfortunately this happened to me last week, one of my drives in a 2
drive LVM started getting all sorts of weird timeouts. It hasn't been
seen since :-(
You can find all this in the docs. In summary: You can start up the
remaining drives with use of the -P (for partial) option to the various
LVM commands (vgscan -P, lvdisplay -P). You can then get back all your
LV's that are complete.
I then made a config backup with vgcfgbackup, edited the config file
(its a text file) to remove the duff drive and did a vgcfgrestore. So
now I have back everything on the good drive. Unfortunately, one of my
LVs was split across the two drives so I lost more than I could have. I
was lucky I hadn't chosen to stripe all the LVs
This wasn't a disaster for me, but it's definitely got me thinking about
RAID and those new seagate 500Gb SATA drives!!!!
