comment high load and OOM-killer on domUs while pvmove
Yesterday i moved some of my LVs. I moved one LV after the other (pvmove -n lvname ...). Most of them moved fine - had no drastic impact on any machine. Now i have 4 LVs left (unfortunately the biggest ones). When i try to move them, load on a domU (always the same one(s)) rises, machine is stuck and i have to abort. Will investigate ... P.S.: Thist was done with running domUs and 'w'-disks

comment high load and OOM-killer on domUs while pvmove
I don't really understand, why 'w!' should make a difference, but i will give it a try. I can't really tell, which memory consumption was going up - as i noticed the oom killer kicking in, i aborted the whole process. But next time i will look into this ... Thank you very much for your input!

comment Xen: Convert image to lvm with minimal downtime
It was pretty fast. About 36h after the initial rsync-run, a second run took ~1/2h (again with lv-snapshot and in background and with running domU). The final rsync run (directly from image to lv - w/o snapshot and domU shut down) even felt faster. I do not have any real data (how much was copied, how many files, ...) because it was so fast, that i had no time to benchmark it ... ;)

comment Xen Bridge only working when IP Assigned
I'm sorry - it's too long ago to remember the details, but: I think i tried the 'ifconfig $INTERFACE up', but i'm not sure about it. The problem was, that the interface needed to have an IP assigned - "up" alone was not enough. But as i said: to long ago ...

BTW: My biggest image took ~36h for the first sync (steps 1-7). Long, but ok, because it ran nicely in background. I wonder how long the second delta-sync will take ...

comment Xen: Convert image to lvm with minimal downtime
Really nice approches, thanks a lot for your ideas! First of all: sure, i use some (many) options for rsync to be sure, i have all my (meta)data copied. I'm aware of the filling lvm-snapshot, but i have enough place to buffer the changes. I really like the md-approach - next time i'll try this. To comment on your DRBD-idea: if i'd go with DRBD, i wouldn't want to mirror each lv by its own, i'd rather mirror the pv(s) via DRBD - nevertheless: nice idea. Anyways, i've already startet with my approach. All works fine, except the sometimes appearing load-jumps on dom0.

comment MySQL Backup and Recover
The .ibd files are not needed in any version of mysql/innodb i know of. It's a matter of configuration if innodb stores data per table in .idb-files (which doesn't mean the 'global' ibdata isn't used / is obsolete) or not.

comment installing mysql via apt-get with non-default data and logs directories
I don't understand the sentence »But that still doesn't solve the problem of finding the rest of the places that the path should go (/etc/apparmor.d/usr.sbin.mysql for a start)« and so don't understand, what your problem is ...

comment installing mysql via apt-get with non-default data and logs directories
I don't really understand what you mean. If don't know the path to your data files, you have an other problem ... ;). If you know the path to your data files, create a file in /etc/mysql/conf.d/ with (an only with) the parameters for mysqld, which you want to overwrite. When mysqld starts, it first reads the /etc/mysql/my.cnf and then files in /etc/mysql/conf.d/ and "rewrites" the given settings. That's all ...

Yes, but why not just create this directory and put your config in there? When installing mysqld it should pick up this config on the very first start, shouldn't it?

comment Xen Bridge only working when IP Assigned
It's been a while, but i'll try to recall: The question is: Why does a brdige need to have a IP-Address in dom0? Why can't i just leave the bridge (here: eth0) unconfigured in dom0 and only add the 'real' interface (here: peth0) and the vifs oft the domUs (here: vif5.1, vif6.1, ...) to the bridge?
