[linux-lvm] Removing disk from raid LVM

Interesting, so maybe it is working, but from looking at the info
you've provided, it's hard to know what happened. I think it might be
time to do some testing with some loopback devices so you can setup
four 100m disks, then put them into a VG and then do some LVs on top
with the RAID5 setup. Then you can see what happens when you remove a
disk, either with 'vgreduce' or by stopping the VG and then removing
a single PV, then re-starting the VG.
Thinking back on it, I suspect the problem was your vgcfgrestore. You
really really really didn't want to do that, because you lied to the
system. Instead of four data disks, with good info, you now had three
good disks, and one blank disk. But you told LVM that the fourth disk
was just fine, so it started to use it. So I bet that when you read
from an LV, it tried to spread the load out and read from all four
disks, so you'd get Good, good, nothing, good data, which just totally
screwed things up.
Sometimes you were ok I bet because the parity data was on the bad
disk, but other times it wasn't so those LVs go corrupted because 1/3
of their data was now garbage. You never let LVM rebuild the data by
refreshing the new disk.
Instead you probably should have done a vgreduce and then vgextend
onto the replacement disk, which probably (maybe, not sure) would have
forced a rebuild.
But I'm going to say that I think you were making a big mistake design
wise here. You should have just setup an MD RAID5 on those four
disks, turn that one MD device into a PV, put that into a VG, then
created your LVs on top of there. When you noticed problems, you
would simple fail the device, shutdown, replace it, then boot up and
once the system was up, you could add the new disk back into the RAID5
MD device and the system would happily rebuild in the background.
Does this make sense? You already use MD for the boot disks, so why
not for the data as well? I know that LVM RAID5 isn't as mature or
supported as it is under MD.
