Macs can’t read LVM disks

Posted on June 16, 2008 by mrjcleaver

From a conversation on IRC’s #lvm channel:

MartinCleaver_: I have a ext3 in lvm filesystem on an external USB drive. How can I mount this on my mac? I have macfuse installed in case that can help.

09:09ambmrMartinCleaver_, afaik, you can’t do that easily
09:09ambmrthe userspace parts of LVM2 will actually build/run on Mac OS
09:09ambmrbut since the Mac kernel has no device-mapper you can’t actually activate your LVM2 volume groups there
09:10amMartinCleaver_Ah, ok, thanks bmr. I’ll stop looking then!

MartinCleaver_Should a Mac running Linux under VMware be able to mount the drive?
09:15a
bmrMartinCleaver_, y – that should work just fine
09:16amMartinCleaver_Heh. The only pity is that the disk I want to mount _contains_ all my vmware images!
09:18ambmrMartinCleaver_, dang
09:18amMartinCleaver_
09:20ambmrMartinCleaver_, have to admit that I use MSDOS partitions on external media for exactly this reason – the benefits of volume management don’t buy me enough to outweigh the problem of not being able to plug them into $random systems
