active/active failover
Hi Stefan, I think what you propose will work, though you should test it thoroughly. I think more generally, "the GlusterFS way" would be to use 2-way replication instead of a distributed volume; then you can lose one of your servers without outage. And re-synchronize when it comes back up. Chances are if you weren't using the SAN volumes; you could have purchased two servers

active/active failover
Hi Alex, Thank you for the quick reply! Yes, I'm aware that using ?plain? hardware with replication is more what GlusterFS is for. I cannot talk about prices where in detail, but for me, it evens more or less out. Moreover, I have more SAN that I'd rather re-use (because of Lustre) than buy new hardware. I'll test more to understand what precisely "replace-brick"

mkdir -p, cp -R fails
Dear all, I have problem with glusterfs 3.12.4 mkdir -p fails with "no data available" when umask is 0022, but works when umask is 0002. Also recursive copy (cp -R or cp -r) fails with "no data available", independly of the umask. See below for an example to reproduce the error. I already tried to change transport from rdma to tcp. (Changing the transport works, but

Add an arbiter when have multiple bricks at same server.
Yes but I want to add.

Managed to make some progress, stuck again.
Hi, An update on my work to integrate my Linux server (CentOS 4.3) in AD 2003. Sorry about the long post :) Found this page (http://www.enterprisenetworkingplanet.com/netos/article.php/3487081) and followed the instructions on it. First, I made sure that the Samba installation is supporting Kerberos, LDAP, AD and Windbind. That was OK. I made sure that /etc/hosts contain the name of the AD

Wrong volume size with df
For what it's worth here, after I added a hot tier to the pool, the brick sizes are now reporting the correct size of all bricks combined instead of just one brick. Not sure if that gives you any clues for this... maybe adding another brick to the pool would have a similar effect?

Blocking IO when hot tier promotion daemon runs
The sizes of the files are extremely varied, there are millions of small (<1 MB) files and thousands of files larger than 1 GB. Attached is the tier log for gluster1 and gluster2. These are full of "demotion failed" messages, which is also shown in the status: [root at pod-sjc1-gluster1 gv0]# gluster volume tier gv0 status Node Promoted files Demoted files

[EXT] Replace broken host, keeping the existing bricks
Hi, The method depends a bit if you use a distributed-only system (like me) or a replicated setting. I'm using a distributed-only setting (many bricks on different servers, but no replication). All my servers boot via network, i.e., on a start, it's like a new host. To rescue the old bricks, just set up a new server this the same OS, the same IP and and the same hostname (!very

Blocking IO when hot tier promotion daemon runs
I should add that additional testing has shown that only accessing files is held up, IO is not interrupted for existing transfers. I think this points to the heat metadata in the sqlite DB for the tier, is it possible that a table is temporarily locked while the promotion daemon runs so the calls to update the access count on files are blocked?

Blocking IO when hot tier promotion daemon runs
Thanks for the info, Hari. Sorry about the bad gluster volume info, I grabbed that from a file not realizing it was out of date. Here's a current configuration showing the active hot tier: [root at pod-sjc1-gluster1 ~]# gluster volume info Volume Name: gv0 Type: Tier Volume ID: d490a9ec-f9c8-4f10-a7f3-e1b6d3ced196 Status: Started Snapshot Count: 13 Number of Bricks: 8 Transport-type: tcp Hot

Blocking IO when hot tier promotion daemon runs
Hi Tom, The volume info doesn't show the hot bricks. I think you have took the volume info output before attaching the hot tier. Can you send the volume info of the current setup where you see this issue. The logs you sent are from a later point in time. The issue is hit earlier than the logs what is available in the log. I need the logs from an earlier time. And along with the entire tier

Gluster cluster on two networks
Hi all! I have setup a replicated/distributed gluster cluster 2 x (2 + 1). Centos 7 and gluster version 3.12.6 on server. All machines have two network interfaces and connected to two different networks, 10.10.0.0/16 (with hostnames in /etc/hosts, gluster version 3.12.6) 192.168.67.0/24 (with ldap, gluster version 3.13.1) Gluster cluster was created on the 10.10.0.0/16 net, gluster peer

NT SMB Support parameter questions
Hi, I've recently had the following experience, which may be of help to people here, so I'm mentioning my tests and conclusions. I've recently been observing this behaviour from Samba - this is an easily reproducible problem:- 1/ Open a share 2/ Create a new document in Word. 3/ Make some changes. 4/ Save the document using the save icon on the toolbar, this works as expected. 5/

Add an arbiter when have multiple bricks at same server.
If you create a volume with replica 2 arbiter 1 you create 2 data bricks that are mirrored (makes 2 file copies) + you create 1 arbiter that holds metadata of all files on these bricks. You "can" create all on the same server, but this makes no sense, because when the server goes down, no files on these disks are accessible anymore, hence why bestpractice is to spread out over 3

Marcus, Can you share server-side gluster peer probe and client-side mount command-lines.
