Subject: Warm swap?
Date: Wed, 17 May 2006 11:11:03 +0100 [thread overview]
Message-ID: <1147860663.4547.122.camel@kenny> (raw)
I played around with RAID1 removeable sata drives on a 2.6.9 kernel
recently (RH Enterprise clone) and basically found that hot-swap killed
the system but warm-swap (remove the disk from all md devices, then pull
it out) worked most of the time. But on one occasion the system froze
when I plugged the disk back in.
What (if any) is the status of warm swap? I don't see it mentioned much
but in terms of its usefulness to a systems manager the difference
between cold-swap and warm-swap is huge, the difference between warm-
swap and hot-swap is tiny. I would MUCH rather have warm-swap now and
hot-swap later than both later if that were possible.
Thanks for all your work on libata.
John
