Hi all, I have setup a dispersed cluster (2+1), version 3.12. The way our users run I guessed that we would get the penalties with dispersed cluster and I was right.... A calculation that usually takes about 48 hours (on a replicaited cluster), now took about 60 hours. There is alot of "small" reads/writes going on in these programs. Is there a way to tune, optimize a dispersed cluster

Hi all, I have setup a dispersed cluster (2+1), verision 3.12. I guessed that we going to get punished by small read/writes... and I was right. A calculation that usually takes 48 hours took about 60 hours and there are many small read/writes to intermediate files that at the end get summed up. Is there a way to tune, optimize a dispersed cluster to work better with small read/writes? Many

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

Hello, We are running glusterfs 6.6 on Ubuntu. We have a Gluster storage system that is a few years old. There are 4 VMs running a Dispersed (NOT replicated) system - a 3 + 1 configuration. Generally performance is well tuned for our needs, but the problem arose last time we added bricks: we attempted a rebalance which is reported as failed. From the mounted POSIX view of the file system, we

Hi, I setup a 4+2 dispersed volume and it worked well so far. ??? gluster volume info ??? Volume Name: disperseVol ??? Type: Disperse ??? Volume ID: 35386b55-829c-4bac-bdba-609427269cf4 ??? Status: Started ??? Snapshot Count: 0 ??? Number of Bricks: 1 x (4 + 2) = 6 ??? Transport-type: tcp ??? Bricks: ??? Brick1: 192.168.129.227:/mnt/gluster/disperseVol ??? Brick2:

Thanks for reading this email?I found a problem while using Glusterfs? First?I created a Distributed Dispersed volume on three nodes?and Limit the volume capacity use quota command?this volume is auto mounted on /run/gluster/VOLUME_NAME. This volume can be read and written normally? After, I manually mounted the volume in another path to provide data storage of SAMBA and ISCSI services, after

If you add bricks to existing volume one host could be down in each three host group, If you recreate the volume with one brick on each host, then two random hosts can be tolerated. Assume s1,s2,s3 are current servers and you add s4,s5,s6 and extend volume. If any two servers in each group goes down you loose data. If you chose random two host the probability you loose data will be %20 in this

Hi Mauro Tridici, >From the information provided it appears like you have placed 2 bricks of a subvolume on one host. Please confirm. The number of hosts that could go down without losing access to data can be derived based on the brick configuration/distribution. Please let us know the brick distribution plan. Regards, Sunil kumar Acharya Senior Software Engineer Red Hat

After adding 3 more nodes you will have 6 nodes and 2 HD on each nodes. It depends on the way you are going to add new bricks on the existing volume 'vol" I think you should remember that in a given EC sub volume of 4+2, at any point of time 2 bricks could be down. When you make 6 * (4+2) to 12 * (4+2) you have to provide path of the bricks you want to add. Suppose you want to add 6

Dear All, I just implemented a (6x(4+2)) DISTRIBUTED DISPERSED gluster (v.3.10) volume based on the following hardware: - 3 gluster servers (each server with 2 CPU 10 cores, 64GB RAM, 12 hard disk SAS 12Gb/s, 10GbE storage network) Now, we need to add 3 new servers with the same hardware configuration respecting the current volume topology. If I'm right, we will obtain a DITRIBUTED

Hello all, attached patch implements Compuserve RPA athentication mechanism. Tested with: - Eudora 6 (uses Compuserve "Virtual Key" RPA software); - TheBat! 2.11 (uses it's own RPA implementation).

Hi When using cut'n paste in word on a 2MB document with different formattings, the paste takes 3 seconds to appear. Tried samba 2.2.8 3.0.1 3.0.2, used different options in speed.txt. Nothing helps. The problem doesn't exsist on a 50KB document, or if i convert the 2MB document to older word 6.0(its size increase to 10MB). Server is SunFire 280R,Antares Quad Gigabit ethernet, Solaris 9.

From: Sebastian Andrzej Siewior <sebastian at breakpoint.cc> This is a huge all-in-one patch and deserves a little cleanup and splitting. However, I wanted to get it out here for some feedback. My primar motivation to use SHA1 for checksumming (by default) instead of MD5 is not the additional security bits but performance. On a decent x86 box the SHA1 performance is almost the same as

Hi, I migrated a PDC to use an ldap backend and am having fun with a few last issues.. Existing user accounts and machine accounts were migrated, and existing users can authenticate. Now I've added some new users and none of them can authenticate. e.g. for the user "inktec". The user can login via SSH, but not mount a share: smbclient \\\\server3\\someshare -U=inktec mypassword

Hi We have a Replica 2 + Arbiter Gluster setup with 3 nodes Server1, Server2 and Server3 where Server3 is the Arbiter node. There are several Gluster volumes ontop of that setup. They all look a bit like this: gluster volume info gv-tier1-vm-01 [...] Number of Bricks: 1 x (2 + 1) = 3 [...] Bricks: Brick1: Server1:/var/data/lv-vm-01 Brick2: Server2:/var/data/lv-vm-01 Brick3:

Hi All! I would be grateful for clarification of my doubts about backups and restoration of the AD environment. What is the best strategy for backing up and restoring a Samba AD domain in the following scenarios: * server1 - active directory service (7 FSMO roles) * server2 - active directory service + Samba file server The considered disaster recovery scenarios are: - Corruption of the AD

Hi, I have a retro LAN running things like Sun SPARCclassics, Ultra1s, Win98 and WinXP. I decided to standardize most of the Sun boxes on the latest versions of OpenBSD that support their architectures (5.9 for Sun4c & Sun4m, 7.4 for Sun4u). I have a Debian 7 server with RAIDs to store all the packages, configs, games, etc. I like to use Samba to transfer the files back and forth between the

Hi All, I am running Samba3.0 beta 3 installed from RPM's provided on the Samba.org FTP server. My platform is Red Hat 9.

Hi. I'm using GlusterFS v1.3.12 (glusterfs-1.3.12.tar.gz) via FUSE (fuse-2.7.3glfs10.tar.gz) on CentOS 5.2 x86_64 (Linux kernel 2.6.18-92.el5) now. The nodes are HP Proliant DL360 G5 (as GlusterFS Client) and DL180 G5 (as GlusterFS Servers). And the connections are all TCP/IP on Gigabit ethernet. Then, I tested self-heal and I found a technical problem about "replace" -- self-heal
