[linux-lvm] Archive Question

[John DeFranco]

Hi All,

I am getting a lot of the following messages:

/etc/lvm/archive/.lvm_ny476.cup.hp.com_24035_984827937: rename to 
/etc/lvm/archive/vgsb1_01871.vg failed: File exists

I don't know is how this happens. I cannot find any documentation on 
this message. Any pointers?

Exactly what version of LVM is this?
(And does the file exist?   Is /etc a local, writeable filesystem?)

Hi,

[root@ny176 log]# lvm version
   LVM version:     2.01.14 (2005-08-04)
   Library version: 1.01.04 (2005-08-02)
   Driver version:  4.4.0

/etc/ is a local writeable filesystem. I believe this occurs when I'm 
issuing a vgchange --addtag and/or vgchange -a y. I have scripts scripts
that are executing these commands but nothing that should be done in 
parallel.

And you have default locking enabled?
  locking_type = 1  locking_dir = "/var/lock/lvm"
  in lvm.conf with /var also local

Perhaps there's some race in the backup file code:
It would be useful to have a list of all the lvm commands that might
possibly be executing against each other.

Yes to all.

I'm trying to assemble that list.

Thanks.
