Hello all, I have just configured a 64-bit CentOS 5.5 machine to support an XFS filesystem as specified in the subject line. The filesystem will be used to store an extremely large number of files (in the tens of millions). Due to its extremely large size, would there be any non-standard XFS build/configuration options I should consider? Thanks. Boris. -------------- next part -------------- An

Does anyone on the list have definitive information on whether ZFS works with CLARiiON devices? bash-3.00# uname -a SunOS XXXXXXX 5.10 Generic_118833-33 sun4u sparc SUNW,Sun-Fire-V245 bash-3.00# powermt display dev=all Pseudo name=emcpower0a CLARiiON ID=APM00033500540 [XXXXXXX] Logical device ID=600601607C550E00F25F4629AFBEDB11 [LUN 61] state=alive; policy=BasicFailover; priority=0; queued-IOs=0

The same thing happens in everithing else like: smbclient

Greetings Samba team, It has been a long time since I needed to ask a Samba technical question. Server and workstation are both running the latest Samba packages via Ubuntu 16.04 LTS. I recently applied the security updates... actually that was yesterday I applied them. > samba (2:4.3.11+dfsg-0ubuntu0.16.04.23) xenial-security; urgency=medium > > * SECURITY UPDATE: client code can

A couple years ago, we moved to Oracle RAC on Linux using ocfs that is SAN attached to an EMC CLARiiON. At the time, there was a reason that we did NOT use EMC's Powerpath (I just can't recall what that reason was). What I'd like to know is if there are any issues with introducing Powerpath now. * RHEL 2.1 AS * 2.4.9-e.38enterprise * ocfs-2.4.9-e-enterprise-1.0.13-1 * EMC

How much fun can you have with a simple thing like powerpath? Here''s the story: I have a (remote) system with access to a couple of EMC LUNs. Originally, I set it up with mpxio and created a simple zpool containing the two LUNs. It''s now been reconfigured to use powerpath instead of mpxio. My problem is that I can''t import the pool. I get: pool: ###### id:

Hi, We had received a new EMC storage (Clariion CX4) and the EMC analist has told us that CentOS aren't on their support list, but RHEL are :) Well anybody on the list has a CentOS host talking (iSCSI) with an EMC storage, preferably using the EMC Powerpath software, and can talk about you experience? Or I will need to buy some REHL licenses ? I'll put my hands on it only next

Hi, over time the requirements and possibilities regarding filesystems changed for our users. currently I'm faced with the question: What might be a good way to provide one big filesystem for a few users which could also be enlarged; backuping the data is not the question. Big in that context is up to couple of 100 TB may be. O.K. I could install one hardware raid with e.g. N big drives

Hi, I got few servers (IBM HS20,HS21 blades, IBM xSeries 3650 & others) connected to a dual fabric san throught Qlogic HBA's (23xx, 24xx). Multipathing is done with device-mapper-multipath. On CentOS 4.x i can scan for new scsi devices without any problems, get them up with multipathing & use them without any problems. However, after i started installing CentOS 5.1 (did not

Hello, I know, that you had this discussion a view days ago but I''m in the installation phase of our new production servers and I intend to migrate the data from UFS volumes to ZFS volumes in near future. For doing this it must be ABSOLUTELY sure that I can resize the SAN LUNs because during the last 4 years I had to double the LUN size every year. I tried to resize a test volume

If anyone is running this configuration, I have some questions for you about Page83 data errors. This message posted from opensolaris.org

We are running a benchmark that does single threaded 512 KB writes to a LUN on a CLARiiON storage array. The dual Xeon host (Dell 2650) with 4 GB of memory runs RHEL 4U3 We measured the write bandwidth for writes to the block device corresponding to the lun (e.g. /dev/sdb), a file in an ext2 filesystem and to a file in an ext3 file system. Write b/w for 512 KB writes Block device 312 MBps Ext2

I would like to change a few things in CUPS, but I would prefer to use the source for the version of CUPS that I already have installed using yum. Mostly because I'm quite happy with the way it works except a few details. Is there a way to get the source using yum or should I go to http://www.cups.org/software.php and get it from there ? The version I installed with yum is 1.1.22 and on

Is there a way to see what repo sites were used by yum? I want to check that my local repos are actually being used.

Hi, I have setup a webserver on CentOS 4.5 with NameVirtualHost. Two VirtualHost should be reachable by port 80 from outside, while the third (default) should be only reachable by https from outside but by http from inside. Since all share the same IP firewalling seems to be out of question. So is there a way to restrict that in Apache config? regards, Andreas

Hi, I have applied traffic shaping on firewall running CentOS 4.5. eth1 is the device where I have done traffic shaping. I am now running some monitoring tools such as polltc and tc-graph.pl. They generate graphs. These graphs are updated every 10 seconds. They have been saved on the firewall it self. To view thsese graphs, I have to enable apache on firewall it self. But I do not need to run
