Already read that. Seems that I have to use a multiple of 512, so 512*(3-2) is 512.

Hi, Before you try turning off the perf translators can you send us the following, So we will make sure that the other things haven't gone wrong. can you send us the log files for tier (would be better if you attach other logs too), the version of gluster you are using, the client, and the output for: gluster v info gluster v get v1 performance.io-cache gluster v get v1

Hi Xavi At this time I'm using 'plain' bricks with XFS. I'll be moving to LVM cached bricks. There is no RAID for data bricks, but I'll be using hardware RAID10 for SSD cache disks (I can use 'writeback' cache in this case). 'small file performance' is the main reason I'm looking at different options, i.e. using formated sparse files. I spent considerable

Have you done any testing with replica 2/3? IIRC my replica 2/3 tests out performed EC on smallfile workloads, it may be worth looking into if you can't get EC up to where you need it to be. -b ----- Original Message ----- > From: "Dmitri Chebotarov" <4dimach at gmail.com> > Cc: "gluster-users" <Gluster-users at gluster.org> > Sent: Tuesday,

Is possible to create a dispersed volume 1+2 ? (Almost the same as replica 3, the same as RAID-6) If yes, how many server I have to add in the future to expand the storage? 1 or 3? -------------- next part -------------- An HTML attachment was scrubbed...

Hi, You have missed the log files. Can you attach them?

Hi At this point I already detached Hot Tier volume to run rebalance. Many volume settings only take effect for the new data (or rebalance), so I thought may this was the case with Hot Tier as well. Once rebalance finishes, I'll re-attache hot tier. cluster.write-freq-threshold and cluster.read-freq-threshold control number of times data is read/write before it moved to hot tier. In my case

Hi I'm looking for an advise on hot tier feature - how can I tell if the hot tier is working? I've attached replicated-distributed hot tier to an EC volume. Yet, I don't think it's working, at least I don't see any files directly on the bricks (only folder structure). 'Status' command has all 0s and 'In progress' for all servers. ~]# gluster volume tier home

Hi, If it was just reads then the tier daemon won't migrate the files to hot tier. If you create a file or write to a file that file will be made available on the hot tier.

Hi, When a brick fails in EC, What is the healing read/write data path? Which processes do the operations? Assume a 2GB file is being healed in 16+4 EC configuration. I was thinking that SHD deamon on failed brick host will read 2GB from network and reconstruct its 100MB chunk and write it on to brick. Is this right?

Hello I'm running some tests to compare performance between Gluster FUSE mount and formated sparse files (located on the same Gluster FUSE mount). The Gluster volume is EC (same for both tests). I'm seeing HUGE difference and trying to figure out why. Here is an example: GlusterFUSE mount: # cd /mnt/glusterfs # rm -f testfile1 ; dd if=/dev/zero of=testfile1 bs=1G count=1 1+0 records

Milind and Hari, Can you please take a look at this?

For the tier daemon to migrate the files for read, few performance translators have to be turned off. By default the performance quick-read and io-cache are turned on. You can turn them off so that the files will be migrated for read.
