Hey, all. I'm currently trying out GlusterFS 3.3. I've got two servers and four clients, all on separate boxes. I've got a Distributed-Replicated volume with 4 bricks, two from each server, and I'm using the FUSE client. I was trying out failover, currently testing for reads. I was reading a big file, using iftop to see which server was actually being read from. I put up an iptables firewall on the active server, and the client hung, as expected. After some time, I guess about 30 seconds, the failover kicked in and the operations went to the other server, resuming the read. However, after going to the other server, throughput went from ~100MB/s to ~25MB/s. Kicking off a new read after the previous one had succeeded went straight to the second server, with throughput still at ~25MB/s. Is this the expected behavior for clients that have failed over from one server to another ? torbjorn at srv18:~$ sudo gluster volume$ Volume Name: testvol$ Type: Distributed-Replicate$ Volume ID: 90636b5d-0d57-483c-bbfd-c0cdab2adaaa$ Status: Started$ Number of Bricks: 2 x 2 = 4$ Transport-type: tcp$ Bricks:$ Brick1: srv18.trollweb.net:/srv/gluster/brick0$ Brick2: srv17.trollweb.net:/srv/gluster/brick0$ Brick3: srv18.trollweb.net:/srv/gluster/brick1$ Brick4: srv17.trollweb.net:/srv/gluster/brick1$ -- Vennlig hilsen Torbj?rn Thorsen Trollweb Solutions AS -------------- next part -------------- An HTML attachment was scrubbed...
