Re: [dm-devel] reboot problem



Device Mapper does not remember the tables you have created across reboots. For persistent volume creation, I would use LVM2.

If you must use device mapper, you could create an init script that creates the devices you've mentioned and mounts "v2". Be forewarned, Linux can reorder block devices, so hard-coding block device names in your init script may result in mapping the wrong device(s). (LVM2 gets around this by writing labels to the devices, so that it can identify the proper devices and assemble them in the correct order.)

Hi all:
I'm a beginner to Device Mapper, now I have a problem perhaps stupid.
However, I have made a mapped device named "v1" with table "t1", then I made a mapped device named "v2" with table "t2" using "v1" as the targed device, and mount "/dev/mapper/v2" at "/mnt/vd".
Now I hope that after reboot there are still "v1","v2" and "v2" will be still mounted at "/mnt/vd". How should I do for these? Thanks!
