Subject: EVMS 2.5.5 questions

Hi all,


I have been using EVMS 2.5.5 on Fedora 7 x64 with great success for a
while now, but I've been collecting some questions along the way that I
cannot seem to find online answers for. I look forward to any insight
from the EVMS community. Thank you in advance!


1) Is there a way, from the EVMS CLI, to find out the % full of a
snapshot? I've run a query:region command on the snapshot region, but
I'm not getting anything there about the % full. (attached is the dump
from the query command)


2) Similarly, is there a way to get a % full on an EVMS volume, even if
there is no file system on it?


3) What method does the snapshot feature use? Is it copy on write, or
something else?


4) When starting EVMS, the EVMS engine log gets full of messages about
failed plug-in loads and failing to open /dev/evms/.nodes/ram devices
(see attached). Is there a way to suppress these messages, maybe
through some setting in evms.conf? Or another way?


5) A previous RAID 6 plug-in for EVMS 2.5.3 was posted by an EVMS
community member. Have people been able to use this with success? I've
noticed that it does seem to work..sort of. Often, volumes created on
RAID 6 regions become deactivated for some reason (don't know why), and
need to be manually reactivated. This does not happen with any other
RAID types.


6) Launching EVMS from the CLI gets slower and slower as more objects
(volumes, regions, etc) are created. Is there any way around this? It
can take 10 seconds or more to start EVMS from the CLI, if I have 30
volumes or more.


Thank you in advance for any input!
