Subject: [linux-lvm] Internal error: Maps lock
Date: Wed, 25 Aug 2010 10:21:20 +0000 (UTC) [thread overview]
Message-ID: <loom.20100825T121646-219@post.gmane.org> (raw)
Hello again.
I'm now running into another problem:
+ /sbin/lvm lvcreate --permission r --snapshot /dev/Sys/Home --name
Home-Backup_Snapshot --extents 15%ORIGIN
Internal error: Maps lock 14004224 < unlock 14266368
Logical volume "Home-Backup_Snapshot" created
What does this "Internal error" mean? Did it actually cause any harm?
I'm confused, because it then goes on to say that the LV was created
and I've also been able to mount "Home-Backup_Snapshot" (it's ext4,
if it matters).
