Subject: Raid1 fast resync
Date: Wed, 01 Jan 2003 10:54:33 -0500 [thread overview]
Message-ID: <3E130F39.3000706@attbi.com> (raw)
Do any of you know of work that is going on to improve the raid 1 resync
speed? I am starting to evaluate approaches to reducing the time to
resync the disks.
I am involved in a project on a fault tolerant x86 based server that has
hot plugable scsi disks and PCI busses. There are two PCI busses and 3
mirrrored sets of two disks. When a PCI bus is pulled all of the mirrors
are broken so when the PCI bus is again inserted, all of the disks
resync which takes hours. Also, during development the resync after
crash really slows down debug.
Thanks,
Phil Cameron
