Subject: device mapper and resizing devices
Date: Tue, 1 Mar 2005 15:03:07 -0600 [thread overview]
Message-ID: <20050301210307.GA28559@thumper2> (raw)
I am using dm-multipath on non-partitioned (xfs) devices on a SAN. If I
resize the device, and rescan my path devices (i.e rescan /dev/sda,
/dev/sdb, /dev/sdc,/dev/sdd (all the same path)) the kernel sees the new
size of the individual devices, but the /sys/block/dm-0 device is still the
old size. I believe this is the reason why I cannot grow my xfs filesystem
without doing a reboot so that the dm device will have the new size. I'd
like to avoid unmounting and rebooting to resize the device. I haven't
played with lvm enough to feel comfortable using it. Is there any way to
get the dm device to be the proper size, or is this a bug, or a feature that
needs further discussion?
Andy
