multiple simultaneous vgmove's?

Can I run multiple vgmove's at one time? I'm moving data from older EVA to newer EVA and am concerned about how long it is taking.

This is an old thread, but thought it deserved somewhat of an answer. I used to do multiple vgmoves when I was using vg version 1.0 volumes. But at that time I was also on an older version of BaseLVM. Currently I am on B.11.31.1303 of BaseLVM and started using vg version 2.2. I have not been able to do multiple moves in this scenario. But what I am unsure of is whether it is a change in LVM or my vg version.

>I have not been able to do multiple moves

Unable how? You get an error? It ignores it? Or takes a long time?

Dennis,

I when I try to do multple vgmoves I get a message stating that the second vgmove cammpt obtain a lock on one of the the lvm files. I cannot rememeber the name off hand. The vgmove command just sits waiting on the lock. I beleive it would eventually go after the first vgmove completes.

This is likely the same as most other LVM related operations.

The command is getting (setting) a lock (file), then executes. If a lock is already set, it waits ... (same if you mirror LVOLs).
