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

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

Hi, We will look into the " failed to get index" error. It shouldn't affect the normal working. Do let us know if you face any other issues. Regards, Hari.

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

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, September 26, 2017 9:57:55 AM > Subject: Re: [Gluster-users] sparse files on EC volume > > Hi Xavi > > At this time I'm using 'plain' bricks with XFS.

Hi I'm looking for an advise to configure a dispersed volume. I have 12 servers and would like to use 10:2 ratio. Yet RH recommends 8:3 or 8:4 in this case: https://access.redhat.com/documentation/en-US/Red_Hat_Storage/3.1/html/Administration_Guide/chap-Recommended-Configuration_Dispersed.html My goal is to create 2PT volume, and going with 10:2 vs 8:3/4 saves a few bricks. With 10:2

Hi I've got a problem on a EC volume where heal doesn't seem to work for just few files (heal info shows no progress for few days, Warning on the client mount) I ran getfattr -m . -d -e hex <brick>/<file> across all servers in the cluster and 'trusted.ec.dirty' attr is non-zero on all files which don't heal. Is it normal? Any way to correct it? It's my

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...

I've had good results with using SSD as LVM cache for gluster bricks ( http://man7.org/linux/man-pages/man7/lvmcache.7.html). I still use XFS on bricks.

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

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

Hello If you use Gluster as FUSE mount it's always slower than you expect it to be. If you want to get better performance out of your oVirt/Gluster storage, try the following: - create a Linux VM in your oVirt environment, assign 4/8/12 virtual disks (Virtual disks are located on your Gluster storage volume). - Boot/configure the VM, then use LVM to create VG/LV with 4 stripes (lvcreate -i
