-Subject: Re: [DRBD-dev] Bad performance when disks mounted with sync but data
-+corruption without sync
-To: Philipp Reisner <philipp.reisner at linbit.com>

-Hi,
-
-I did some testing, and I think I know what gave me the bad throughput
-
-I rebuild the filesystem on /dev/nb0 with reiserfs v3.6 in order not to
-have to use the sync option for mounting /dev/nbo
-on the server. This didn't give me a good throughput, but it doubled
-from 64kB/sec to 128kB/sec, without data corruption on failover.
-
-I discovered I was using the sync option while mounting the filesystem
-on the workstation. I turned this off and guess what,
-througput now is about 2.5MB/sec, also without data-corruption during
-fail-over.
-
-I was wondering what would happen if I also turned off sync and
-no_wdelay on the server.
-Well, I tried and througput was 4.2MB/sec BUT I got DATA-CORRUPTION
-during failover.
-
-Conclusions:
-
-If using a non-journalling filesystem like ext2 one should mount
-/dev/nb0 with the sync option. (Why things where messed up for me using
-ext3 is still not clear to me). The sync option is not needed for
-journalling filesystems like reiserfs
-Example fstab entries (Just use one for each nbd device) for mounting
-/dev/nb0 on /drbd0:
-/dev/nb0 /drbd0 ext2 noauto,sync 0 0
-/dev/nb0 /drbd0 reiserfs noauto 0 0
-
-Use the sync and no_wdelay option in your /etc/exports file on the
-server or else you will get data-corruption on fail-over
-Exampe exports entries:
-/drbd0/export *(rw,no_root_squash,sync,no_wdelay)
-
-Do NOT USE THE SYNC OPTION while mounting the NFS filesystem on your
-client (workstation). When you do, things
-will slow down terribly

-Subject: [DRBD-dev] Stale NFS handles
-Date: Tue, 05 Mar 2002 16:27:34 +0100
-
-Hello,
-
-I read some messages about stale NFS handles and I thought some of you
-would be interested in this information.
-Until a few hours ago I got Stale NFS handles during fail-back
-operation, and it was reproducable.
-I first thought there was something wrong with DRBD's sync or that it
-had to do with heartbeat, but no, it
-was my nfsserver script that was causing them.
-In my nfsserver script there was the following line:
-/usr/sbin/exportfs -au
-This causes an unexport of all directories, which means that your server
-is really telling to its clients that it is going down, and this
-definitly is something YOU DO NOT WANT TO HAPPEN.
-Just execute the command on your server while copying big files to your
-server and look at the screen of your workstation.
-
-So, if you don't want the Stale NFS handles to occur, just get rid of
-the line containing something like /usr/sbin/exportfs -au
-And, do not forget to do the same for the script in the /etc/rc.d (or
-/etc/init.d) directory or you will still get the same
-to happen when rebooting your fileserver (the one that is actually
-exporting the filesystem at that moment)
-
-Regards, Erik de Wilde
