I concur with the OP on this convention. My usage scenario is different though. Most of my linux boxes are on VMware and I rely on cloning and templates a great deal. I leave the vg name generic so the templates are less messy. I don't have to worry about SAN naming conventions because my SAN storage is vmfs first, before files are carved out and handed to VMs. I suppose I could add a vg_rename as part of my cloning/templating instantiation process, but I'm unlikely to pass disks around. -- Jess ________________________________________ From: linux-lvm-bounces@redhat.com [linux-lvm-bounces@redhat.com] On Behalf Of James Hawtin [oolon@ankh.org] Sent: Wednesday, April 20, 2011 5:01 AM To: LVM general discussion and development Subject: Re: LVM Naming Convention Assarsson, Emil wrote: > We have also started to use hostnames in the VG names for the same reason. Starting with vg makes is easier to auto complete when using bash :-P. I don't see any reason why to use "lv" to the LV's but it doesn't hurt. I also try to use UUID's in the /etc/fstab as much as possible. > > Best regards > Emil Assarsson > I also use the hostname in the volume group name for all the reasons already suggest, its particularly valuable when dealing with san disk, as any mistake is very obvious. personally I use /dev/<hostname>_<type><number>_vg/<filesystem>_lv Where type is l for local disk s for san. I keep my raid 1 and raid 5 in different volume groups to avoid mistakes, however both are called l or s. Where the disk is for use to virtual machines I used /dev/<hostname>_<type><number>_vg/<virtual machine>_v<number>_lv I put _vg at the end of all volume groups mostly for completeness, and avoidance of any change of a name clash, I also thing _lv is useful as alots of devices can be mixed up in /dev/mapper so giving them a seperate namespace so the don't get mixed up with multipathed disk, (and in the old days raw devices) etc. I can do a ls /dev/mapper/*_lv to see all my logical volumes all in one go, independant of group.
