Subject: File as generic block-device?
Date: Wed, 22 Oct 2008 14:56:36 +0200 [thread overview]
Message-ID: <48FF2304.8070301@dolphinics.no> (raw)
Hi all,
I have a project where I require to treat a file as a block-device
(specifically, I want a file on an ext3 fs to act as one of the
raid-members in a md-based stripe-set. I know that I can make a
/filesystem/ on a file because both mkfs and mount (with -o loop) will
accept a file as a block-device, but I have found no such function for
mdadm, and am thus asking for a kernel-internal way to re-plug a file
into the block-device layer.
Is this possible?
My current platform i CentOS5, a RHEL5 rebuild (modified 2.6.18-kernel).
