09:27 andreas hi all, is there a way to read all the bricks on a replica 3 volume? or is there a way to convert a replica volume to a striped volume?

09:36 andreas cool. can I convert replica to shard? or read all the bricks while reading a file on a replica volume?

09:52 ivan_rossi andreas: IIRC to convert replica to shards you need to manually copy ALL the files, once the volume is sharded....
09:53 ivan_rossi not a feasible task, most of the times

15:33 huddy Hi - I've got two servers one that has data on it, in RAID, and another that's about to provisioned and I'm wondering if it's possible to use glusterfs in this example? I want to pool both the servers storage together.
15:34 susant joined #gluster
15:35 susant joined #gluster
15:35 huddy also should it, can it be used on RAID?

15:41 andreas raid is an uderlaying layer. glusterfs is not bothered about it.
15:43 andreas I got 4 different md5 sum on 4 different clients for the same file on sharded volume. i'm scared.

15:49 huddy andreas: fair enough. so without raid can glusterfs survive a single disk failure? if not i'll setup raid. in addition the docs say two nodes required to get going. do they have to be the same size? I'm thinking that I'll setup the new large storage server with gluster and migrate the data over, and then turn the existing server (which at this point would have moved it's data over to the new glusterfs cluster) into a
15:49 huddy gluster node and join it to the cluster. I've got a smaller server I could make the second node for now.
15:51 andreas you can run glusterfs volumes in several modes, like distributed, replicated. each has different fault tolerancy.
15:52 andreas disk with same size: does not matter. gluster operates in top of ordinary filesystem (xfs, extfs, etc)
15:54 jiffin joined #gluster
16:00 huddy andreas:  which volume type would you recommend for essentially pooling two servers together to get double storage of a single server whilst still being able to survive 1 or 2 disk failures? I'm not expecting to be able to survive a server failure - but on that question actually if one node goes down can data on the other node still be written / read?
16:01 huddy based on what I've read Distributed Striped Glusterfs Volume is the one I need
16:01 huddy as this striped the data on accross bricks on each node
16:02 huddy i'm being dumb, i meant Distributed Replicated Glusterfs Volume
16:03 huddy obviously stripe would mean I couldn't lose a disk
16:03 huddy or brick as gluster calls it :P

19:19 huddy I got a nice warning about not putting volumes/bricks on root partitions  - what are the implications of doing that anyway?
19:20 plarsen joined #gluster
19:26 plarsen joined #gluster
19:27 JoeJulian huddy: mostly for safety. Typically a brick is on its own filesystem on a storage device of some sort that's mounted. If, for some reason, the device fails to mount at boot you don't want gluster to start replicating everything from the other brick(s) to your root filesystem.
