I am working currently on cloning on a regular basis our production OCFS2 volumes to our test environment. For the database (Oracle 10G R2 RAC) we put it into backup mode, then execute a Snapclone on our 3Par SAN. Then we use RemoteCopy and SnapClone to our development 3Par SAN. To recover the OCFS2 volume I got through the following steps: Stop database umount /export/<volume name> Log into SAN to refresh Snapclone fsck.ocfs -y /dev/mapper/<volume name> mount /export/<volume name> u...

We just installed a new cluster with 6 HP DL380g5, dual single port Qlogic 24xx HBAs connected via two HP 4/16 Storageworks switches to a 3Par S400. We are using the 3Par recommended config for the Qlogic driver and device-mapper-multipath giving us 4 paths to the SAN. We do see some SCSI errors where DM-MP is failing a path after get a 0x2000 error from the SAN controller, but the path gets puts back in service in less then 10 seconds....

We are setting up 2 new EL5 U4 machines to replace our current database servers running our demo environment. We use 3Par SANs and their snap clone options. The current production system we snap clone from is EL4 U5 with ocfs2 1.2.9, the new servers have ocfs2 1.4.3 installed. Part of the refresh process is to run fsck.ocfs2 on the volume to recover, but right now as I am trying to run it on our 700GB volume it shows...

Hi Friends, I am currently using Samba on Centos 4.4 as a domain member of AD 2003 with each user having a quota of 2GB(no of users is around 2,000). Now the management wants to increase the quota to 10GB with this there will be more than 20TB of data to be backup weekly which will take lots of hours. Currently Veritas backup software is used to backup data on tapes. There is a concept of

As RedHat has a limited choice of file systems it supports, I have a need to use EXT3 together with Oracle and a SAN SnapShot (3Par Snapclone). I was wondering if anyone could give me some feed back as to the "best" method to do that. So far I am thinking: Put Oracle into Backup mode Run sync (or multiple times) Execute Snapshot command on SAN (takes less then 1 second). Take Oracle out of Backup mode Then on the s...

Hi all, Sorry for the OT. I've got an IBM N3300-A10 NAS. It runs Data Ontap 7.2.5.1. The problem is, from the docs it says that it only supports either RAID-DP or RAID4. What I want to achieve is Max Storage Capacity, so I change it from RAID-DP to RAID4, but with RAID4, the maximum disk in a RAID Group decrease from 14 to 7. In the end, either using RAID-DP or RAID4, the capacity is the same.

On a similar note to Joe''s email below, I am looking for metrics or documents concerning disk I/O performances for Xen 3.3.x. More specifically, what are the performance gains observed between FC SAN (Emc, Hitachi, 3Par..), iSCSI, NFS, SATA, and SAS disk storage? Are there any domU image layout and tune up recommended?

Just started messing with multipath against an iSCSI target with 4 nics. What should one expect as behavior when paths start failing? My lab setup was copying some data on a mounted block device when I dropped 3 of 4 paths and the responsiveness of the server completely tanked for several minutes. Is that still expected? Thanks, jlc

...d the RFC implies it might be desirable to support larger sizes in some channels. What determines what the absolute maximum is in openssh sshd? Presumably no client can negotiate a maximum that is larger than that advertised by the server?

I saw this in the openfiler thread, and realised it is another major hole in my knowledge What do you all use for clustering, and does it run out-of-the-box with CentOS? My main areas of interest are : - DB clustering (PostgreSQL) - yeah, we're looking at commercial stuff and skytools - web server clustering - Apache on CentOS - storage clustering thanks, -Alan -- ?Don't eat anything

Hello Everyone I work for a University Department that has a high number of Linux Desktop Users. Currently we provide a users home directory via NFS from a file server. Generally it works well for us, but I have been asked to look at our options for expanding the storage we have available. So I thought one of the first things I had better do is consider are there alternatives to the way we

I'm looking for RAID options for at least 10 TB to attach to a Dell PowerEdge 2950 running RHEL 5 64-bit Server. The system will act as a single sign-on server for XP and Linux, thus storing user's data from mounted home directories exported from the server to various workstations. It may also house a database. I'll need a storage solution starting at least 10 TB. Most of the

Hi all. I am currently working for a hosting provider in a 100+ linux hosts' environment. We have www, mail HA solutions, as storage we mainly use NFS at the moment. We are also using DRBD, Heartbeat, Corosync. I am now gathering info to make a cluster with: - two virtualization nodes (active master and passive slave); - two storage nodes (for vm files) used by mentioned virtualization nodes

Hello, We have long running problem with NetApp filers. When we connect server to the filer sequential read performance is ~70MB/s. But once we run database on the server seq read performance drops to ~11MB/s. That's happening with two servers. One is running Oracle another - MySQL. During speed tests database load is very light (less than 1MB/s of reads and writes). During the tests NetApp

I've found a lot of posts with "same" problems but without the magic answer :-) First, the environment: - HP 3par SAN, 2 TB LUN (no SAN storage related performance problems - already checked) - qlogic HBA (4 path), round robin with multipath - kernel 3.2.0-4-amd64 - 5 cluster nodes - ocfs2 version 1.6.4 - 480 million inodes in use, iUse% = 92 - OCFS was made with: "mkfs.ocfs2 -b 4k -C 4k -N 8 -L myocfs -T...

Hi, We are in the process of testing a migration of our current setup which contains Samba 4 as Classic DC with LDAP backend, Isilon OneFS bulk storage serving NFS/SMB shares and Windows/Mac/Linux clients to a more modern Samba 4 AD. We need to migrate to Samba AD because of Windows 10 and macos 10.13.x (and for several other reasons). But we run into an issue with authenticating the clients

Hi, I just received a Supermicro server back from factory repair. Installed CentOS 6.3 x86_64 fresh from DVD (tried with 6.4, same result). Everything goes fine until i install Virtualization* yum groups. Virtualization is enabled in BIOS. Server boots, CentOS loads and i have even a login prompt. If i'm fast enough to enter login name and password, shell works for about 10 sec.

Hi, I'm looking at using Linux as a NAS / SAN device, and would like some input from other's who have done this before? How would it compare to commercial SAN devices, Thecus N8800SAS (http://www.thecus.com/products_over.php?cid=11&pid=177&set_language=english) or something similar to these? I would probably use hardware RAID 10, and could go with either SAS / SATA, and then
