Subject: Overlay ramdisk on filesystem?
Date: Thu, 15 Apr 2004 17:08:20 -0400 [thread overview]
Message-ID: <407EF9C4.4070207@techsource.com> (raw)
I have a feeling that this may be a bit too off-topic, but I'm doing
some Linux and hardware performance tests, and some of the tests will
put the hardware into an unstable state which could get memory errors
which could cause filesystem corruption.
I would like to know how I could overlay a RAM disk over a read-only
filesystem so that all new files and modified files end up in the RAM
disk, but old files are read from the disk. This way, when I reboot,
the disk reverts back.
Suggestions?
Thanks.
