The '-' character is allowed: # vgrename t0 t0-foo Volume group "t0" successfully renamed to "t0-foo" Sounds like this is the installer enforcing an additional restriction.

It's bug in kickstart processing - lvm allows '-' in vgname.

Sorry for that: If you send me the ticket number privately I'll see that it's progressed. > Would you aggree that a short note about allowable names should be added > to man lvm? If yes, then I don't mind creating a patch. Here's a current summary of the rules (as added to bug 430907). The characters allowed in VG and LV names are: a-z A-Z 0-9 + _ . - Neither a VG nor an LV can begin with a hyphen. There are also various reserved names. A VG cannot be called anything that appears in 'ls /dev' at the time it is created (including '.' and '..' of course). An LV can also not be called '.' or '..'. A new LV cannot begin with the strings 'snapshot' or 'pvmove'. It may not contain the strings '_mlog' or '_mimage'. Additional reserved strings are likely to be added over time. Pre-existing LVs may be found with these names, and the tools will normally cope adequately. (Internally-generated LVs do use these reserved names - that's why they are reserved.)

If a reserved name is discovered when activating a VG, rename it to something legal but recognizable. I remember when this used to cause problems on AIX - because all LVs had to be unique, so importing a foreign VG would rename all the common LV names - very annoying. But this is not a big problem with lvm2 because only the VG needs to be unique. - -- Stuart D. Gathman Business Management Systems Inc.
