similar to: CentOS and LessFS

Hi, I'm currently running GlusterFS over XFS, and it works quite well. I'm wondering if it's possible to add data deduplication into the mix by: glusterfs --> lessfs --> xfs or glusterfs --> opendedupe --> xfs Has anybody tried doing this? We're running VM images on gluster, and I figure we could get a bit of space saving bu deduplicating the data. Gerald

Hi all, Back in March someone asked about deduplication in Centos and I replied I'm using LessFS. I want to report that my overall experience is that I have performance issue up to the point that I would like to abandon it. The OP was asking http://www.opendedup.org/ How is it? Thanks Fajar

Hi list, is there any working solution for deduplication of data for centos? We are trying to find a solution for our backup server which runs a bash script invoking xdelta(3). But having this functionality in fs is much more friendly... We have looked into lessfs, sdfs and ddar. Are these filesystems ready to use (on centos)? ddar is sthg different, I know. Thx Rainer

CentOS 6 Hi All: Over the weekend I had to reboot one of my systems and got hit with fsck runs on all of the filesystems. I would not mind so much except doing them all at once took over an hour. I would like to be able to stagger these, ideally only execute one fsck per reboot. I have been able to think of two possible solutions but neither is terrific. My first idea was to manually run fsck

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Hi, A feature of Cyrus-IMAPd I really missed after migrated to Dovecot is their optional "duplicate suppression", which eliminates duplicate message at deliver time, if their envelope sender, recipient and message-id matches. For example, if one subscribes to a mailing list, and someone hit "Reply All" to reply to him, there

CentOS 4.8, BIND 9.2.4 Hi All: I have a rather annoying problem with rndc which I have not been able to resolve despite much searching and many attempts to correct. When making changes to our DNS entries I have tried to use the following procedures: 1. Flush the cache buffers: rndc flush 2. Stop named: rndc stop 3. Delete the journal files: rm *.jnl 4. Edit the forward and/or

I am trying to avoid running them at the same time in an effort to avoid 70 minute boot times (which is

Hi All: I am looking for some possible recommendations on the handling of our internal DNS services. First some background... Until recently our entire network was located within a single facility with internal DNS services provided by our CentOS 4.7 (using BIND). While I had problems with DHCP/DNS communications it was basically working. At the beginning of the month we moved the production

CentOS 6.5 Hi All: We are looking for a way to automate the handling of bounced emails. I have spend some time looking an scan find one open source package, bounceHammer, and one commercial package, BoogieTools. Does any comments on the effectiveness of either package?

Hi All: Is there a utility available that will allow for the dump/display of the bad track table of a SCSI drive. We had this capability on SCO OSR5 but I have not been able to locate anything similar for Linux. The closest I have found is the badblocks utility that is part of the e2fsprogs package but this appears to only test for bad blocks not display the current bad block table contents. I

Hi All: Over the weekend I install all the outstanding updates for our CentOS 4 based server. Since I had been holding off on these until I had addressed some disk space issues there were a large number (300+). I know my bad! After installing the updates I rebooted the system and it took forever to boot and once up there were problems connecting to some of our SAMBA shares. I checked the messages

CentOS 4.8, BIND 9.2.4, DHCP 3.0.1 Hi All: I have a rather perplexing problem where the DNS entry in BIND for one of my network printers sporadically "disappears" from our zone file (but not the reverse zone file). We have four Lexmark printers connected locally over our internal LAN using static IP addresses. We have 3 T640n printers and a T642n printer and it is only the T642n

Hi all: I have a situation where I need to change the distribution of emails for selected accounts on a regular basis. This is for the controlling of the distribution of our "support" email address. In the past I just created a "alias.bas" file to hold the bulk of our aliases and then 3 "support" alias files, alias.wkd, alias.evn and alias.wed (for weekday, evening
