[Gluster-users] Enable sharding on active volume

2018-04-04 Thread Ian Halliday
Hello, I wanted to post this as a question to the group before we go launch it in a test environment. Will Gluster handle enabling sharding on an existing distributed-replicated environment, and is it safe to do? The environment in question is a VM image storage cluster with some disk files

After updating the test server to 4.0.1, I can indeed confirm that so far the disappearing directories bug is gone. On Wed, Apr 4, 2018, 8:29 PM Raghavendra Gowdappa wrote: > Can you check whether you are hitting > https://bugzilla.redhat.com/show_bug.cgi?id=1512437? Note

Hi, I'm currently facing the same behaviour.  Today, one of my users tried to delete a folder. It failed, saying the directory wasn't empty. ls -lah showed an empty folder but on the bricks I found some files. Renaming the directory caused it to reappear. We're running gluster 3.12.7-1 on

This sounds like it may be a different issue. Can you file a bug for this ([1]) and provide all the logs/information you have on this (dir name, files on bricks, mount logs etc)? Thanks, Nithya [1] https://bugzilla.redhat.com/enter_bug.cgi?product=GlusterFS On 4 April 2018 at 19:03, Gudrun

Based on your message, it sounds like your total usable capacity requirement is around <1TB. With a modern SSD, you'll get something like 40k theoretical IOPs for 4k I/O size. You don't mention budget. What is your budget? You mention "4MB operations", where is that requirement coming from?

thanks for your reply, Yes the VMs are very small and provide only a single service, I would prefer a total of 2TB but 1TB to start is sufficient. Ideally I want a scheme that is easy to expand by dropping an extra disk in each node. When all slots are full, add another node. our current setup

Hi, Trying to make the most of a limited budget. I need fast I/O for operations under 4MB, and high availability of VMs in an Ovirt cluster. I Have 3 nodes running Ovirt and want to rebuild them with hardware for converging storage. Should I use 2 960GB SSDs in RAID1 in each node, replica 3?

[Gluster-users] Expand distributed replicated volume with new set of smaller bricks

We currently have a 3 node gluster setup each has a 100TB brick (total 300TB, usable 100TB due to replica factor 3) We would like to expand the existing volume by adding another 3 nodes, but each will only have a 50TB brick. I think this is possible, but will it affect gluster performance and if

Hi, Yes this is possible. Make sure you have cluster.weighted-rebalance enabled for the volume and run rebalance with the start force option. Which version of gluster are you running (we fixed a bug around this a while ago)? Regards, Nithya On 4 April 2018 at 11:36, Anh Vo
