Than you so much for this reply. We used to have client-side replication<br>
and failover worked very nice, but we were unable to do auto-restore<br>
(servers do not know about each other), thus I thought that moving<br>
tovards server-side replication would be a good idea.<br>
<br>
We will probably move back to client-size and do the rsync-like<br>
auto-restore after storage node failure.<br>
<br>
Again thanks, that helped me a lot, since now I have at least startpoint<br>
what to expect and whan not (regarding GlusterFS).<br>
<br>
PS: I like the GlusterFS architecture concept, and config files as well.<div><div></div><div class="h5"><br>

Hi.<br>
<br>
2009/4/1 Ondrej Jombik <<a href="mailto:nepto@platon.sk" target="_blank">nepto@platon.sk</a>><br>
I'm trying to configure GlusterFS setup with two replicating servers.<br>
For now just without any client. Worked well so far, however after<br>
I rebooted the second server I started to have difficult times...<br>
(note: first server remains unrebooted)<br>
<br>
<br>
Advice - use client side replication, it's considered more reliable and supports fail-over.<br>
<br>
<br>
1. are all changes made on non-rebooted server during the second server<br>
reboot lost? they are not replicated after rebooted server is online<br>
again... is there OFFICIAL way how to acheive this? Does it have some<br>
binary log of non-performed write operations?<br>
<br>
<br>
You only need to run ls -lR when the server comes up to sync between the files. Now, only if it always worked... <br>
<br>
<br>
6. option favorite-child remote<br>
This does nothing as well, but at least print some warning into the<br>
log files. However what is written in the warning actually does not<br>
happen. I tried to access all files on remote/local<br>
device/mountpoint (4 ways), no change at all.<br>
<br>
<br>
Happens to me to.<br>
<br>
<br>
7. if I define "subvolumes remote" (so kicking local from subvolumes)<br>
than I finally get the right file contents, but only at mountpoint,<br>
not in actual device; I need to get files into the actual device<br>
(local disk) of rebooted server<br>
<br>
<br>
Happen to me to.<br>
<br>
<br>
8. and finally I deleted all the files from device of rebooted server<br>
and I was hopping for the replication to do the rest; and viola,<br>
I have them replicated, so all files created during reboot are there,<br>
but they are all filed with zeros!<br>
(and no this is not that known XFS bug, it is actually on EXT3)<br>
<br>
<br>
Welcome to the club :).<br>
<br>
<br>
I know this all is pretty incredible and looks like a horror story, but<br>
I have read tons of documentation and still I'm not able to figure that<br>
out. I wish that it is problem between keyboard and chair and not in the<br>
software itself.<br>
<br>
I'm only trying to have RAID-1 over network with automatic recovery<br>
after reboot/outage. Is this that complicated??<br>
<br>
(I need to metion that I did not started with clients yet, there I'm<br>
expecting even bigger troubles like this)<br>
<br>
<br>
As I said, perhaps you should try client-side AFR first?<br>
