Hi all,
Sometimes, I see the following message in the VG metadata backups
under
/etc/lvm/archive:
"""
contents = "Text Format Volume Group"
version = 1
description = "Created *before* executing 'vgs'"
"""
I'm wondering when and why the new backups will be created by
reporting
command like vgs?
It's probably a case where lvm sees something wrong after reading the
VG
metadata, and automatically tries to fix it, writing a corrected
version
of the metadata to disk. This means that even a command that only
reads
and reports lvm information can potentially write to disk.
Interesting. Eric, can you show the *before* and *after* vgs textual
metadata (you should find them in /etc/lvm/archive)?
that in theory are only reading and reporting information. I've also
suggested that whenever repairs are done, lvm should record a
persistent
message in the system log with the details, but that idea didn't get a
great reception.
Just to know: why the idea of syslog reporting was discarded?
Thanks.
