similar to: default cluster.stripe-block-size for striped volumes on 3.0.x vs 3.3 beta (128kb), performance change if i reduce to a smaller block size?

Hi, I've got this strange problem where a striped endpoint will crash when I try to use cp to copy files off of it but not when I use rsync to copy files off: [user at gluster5 user]$ cp -r Python-2.6.4/ ~/tmp/ cp: reading `Python-2.6.4/Lib/lib2to3/tests/data/fixers/myfixes/__init__.py': Software caused connection abort cp: closing

which is a stripe of the gluster storage servers, this is the performance I get (note use a file size > amount of RAM on client and server systems, 13GB in this case) : 4k block size : 111 pir4:/pirstripe% /sb/admin/scripts/nfsSpeedTest -s 13g -y pir4: Write test (dd): 142.281 MB/s 1138.247 mbps 93.561 seconds pir4: Read test (dd): 274.321 MB/s 2194.570 mbps 48.527 seconds testing from 8k -

In IRC today, someone who was hitting that same IB performance ceiling that occasionally gets reported had this to say [11:50] <nissim> first, I ran fedora which is not supported by Mellanox OFED distro [11:50] <nissim> so I moved to CentOS 6.3 [11:51] <nissim> next I removed all distibution related infiniband rpms and build the latest OFED package [11:52] <nissim>

Hi, Running samba sernet 4.1.6-7, I've noticed the load avg slowly / steadily creeping up (.e.g > 100). I'm now noticing that several smbd processes are at 100%. I don't actually notice that much bandwidth usage on the system (e.g. iptraf/iftop). Any idea what's causing this? Restarting smbd helps for a few days, but then the high load avg returns. Thanks, Sabuj

I'm about to do some testing with a an OSX 10.9 client connected to sernet samba 4.1.5 to see what things work and don't both from the finder and from the terminal with unix extensions = yes and no. Does anyone know of any show stopping issues that occur with unix extensions = yes and the latest samba (or 3.6.x, or 4.0.x a) and the latest OSX (or latest update with 10.7 & 10.8)?

Hi, Anyone know if the 1024 char limit for auth.allow still exists in the latest production version (seems to be there in 3.2.5). Also anyone know if the new versions check if auth.allow has been updated without having to restart glusterd? Is there anyway to restart glusterd without killing it and restarting the process, is kill -1 (HUP) possible with it (also with the version i'm running?)

Hi, Why does mkfs.ocfs2 take so long compared to gfs2 (pretty fast iirc), xfs (almost instantaneous), or ext3 (slow but still ok)? I'm using: # mkfs.ocfs2 -F -b 4k -C 4k -L san1 -T mail /dev/vg/san1 mkfs.ocfs2 1.3.9 Overwriting existing ocfs2 partition. WARNING: Cluster check disabled.

Hi all, We're running gpfs 3.5.0.12 (5 total nsds & quorum servers, 2 nsds running samba), sernet-samba 4.1.4-7, and ctdb 1.0.114.7-1 and trying to get transparent failover to work from a windows 8 client. We have ctdb failover working, i.e. if I run mmshutdown on one of the nodes the IPs failover in a few seconds after the GPFS mount is unmounted. For our transparent failover test, I

All, For our project, we bought 8 new Supermicro servers. Each server is a quad-core Intel cpu with 2U chassis supporting 8 x 7200 RPM Sata drives. To start out, we only populated 2 x 2TB enterprise drives in each server and added all 8 peers with their total of 16 drives as bricks to our gluster pool as distributed replicated (2). The replica worked as follows: 1.1 -> 2.1 1.2

Hi, I noticed that smbcontrol smbd reload-config or service smbd reload doesn't reload include files. Is there anyway to get a reload to reload files that have been included from the main smb.conf ? Otherwise it only looks like restart works, but that causes connections to reset, even in a ctdb/clustered environment . The only other option it looks like is to just put everything into the

Hi all, I have two rhel 6.3 servers running sernet samba 4.1.4-7 with winbind connecting to AD. They're also running ctdb. For some very strange reason I can't get one specific AD group to show up in the output of "id username" or the gid of that group to show up in "wbinfo -r username" for the user on one of the servers but it shows up fine on the other. The strange

I noticed that vfs_acl_xattr doesn't work unless all the inherit and map inherit acl parameters are set to yes. Which is fine but if I turn off inherit owner it completely breaks inheritance and security.NTACL never gets set for the file/directory that's created by the user. I want the uid of the user who's connected to be written and not the owner of the parent directory. Is there

Hi all, Does anyone have vfs_shadow_copy2 working with an alternate snapshot directory format? My snapshots look like this : drwxr-xr-x 55 root root 32768 Jan 10 12:37 20140113_12:00 drwxr-xr-x 55 root root 32768 Jan 10 12:37 20140114_12:00 drwxr-xr-x 55 root root 32768 Jan 10 12:37 20140115_12:00 drwxr-xr-x 55 root root 32768 Jan 10 12:37 20140116_12:00 drwxr-xr-x 55 root root 32768 Jan 10

Greetings, There are 2 imminent releases coming soon to a download server near you: 1. GlusterFS 3.2.6 - a maintenance release that fixes some bugs. 2. GlusterFS 3.3 beta 3 - the next iteration of the exciting new hotness that will be 3.3 You can find both of these in the "QA builds" server: http://bits.gluster.com/pub/gluster/glusterfs/ There are source tarballs and binary RPMs

Hi- I'm new to Gluster, but am trying to get it set up on a new compute cluster we're building. We picked Gluster for one of our cluster file systems (we're also using Lustre for fast scratch space), but the Gluster performance has been so bad that I think maybe we have a configuration problem -- perhaps we're missing a tuning parameter that would help, but I can't find

Hi, Can you send the volume info, and volume status output and the tier logs. And I need to know the size of the files that are being stored.

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

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
