Hi all, is there a function (or variable) I can use in a custom init script that identifies the init script name? i.e. I'm porting some init scripts from gentoo, where the $SVCNAME variable identifies the init script name within the script itself... d /* Davide Cittaro Cogentech - Consortium for Genomic Technologies via adamello, 16 20139 Milano Italy tel.: +39(02)574303007 e-mail:

Hi all, I'm new to Centos, just moved here from Gentoo Linux. I have to install a server for bioinformatics purposes and I see that default yum repositories do not include any bioinformatics software (i.e. ncbi-toolkit, blat, and others). I'm googling a bit but I can't find a valuable solution: which is (or which are) the best repository I should add to have a satisfying list

Hi, I was hoping someone would have an idea of what's going on here... We have two NFS issues. One of which is certainly centos based, one of which we're not sure of. First issue is: As of Centos 5, we can't make simultaneous access to a directory via NFS. To duplicate, I cd into a share in two windows, copy a 1G file in the first window, and just do an ls in the other. The ls

Hi all, Is there a way to dump the current packages installed on a machine and use it do install/uninstall packages on other machines? I've configured one at install time but to speed up other installations I would like to install default packages and then install/uninstall some starting from my first machine configuration... thanks d PS Oh, I'm going to RTFM too... but I'm

Well, apparently there WAS a change on the Windows Server, which only affected new samba versions I was able to fix my issue by using this patch: https://bugzilla.samba.org/show_bug.cgi?id=12776 Can this be officially fixed please? >-----Original Message----- >From: Lange Norbert >Sent: Dienstag, 08.

I am planning to use ZFS on my Centos 5.2 systems. The data I am storing is very large text files where each file can range from 10M to 20G. I am very interested on the compression feature of ZFS, and it seems no other native Linux FS supports it. My question are: Is ZFS stable? How does it scale for very large filesytems, ie, 2TB to 9TB? How is the performance of fuse? I plan to use it on my

Hi, We have a storage server (HP DL360G5 + MSA20 (12 disks in RAID 6) on a SmartArray6400). 10 directories are exported through nfs to 10 clients (rsize=32768,wsize=32768,soft,intr,nosuid,proto=udp,vers=3). The server is apparently not doing much but... we have very high waiting IOs. dstat show very little activity, but high 'wai'... # dstat ----total-cpu-usage---- -dsk/total-

Hello, Does anybody know how to avoid the file fragmentation when a file is created over NFSv3? A file created locally is OK: dd bs=32k if=/dev/zero of=test count=32x1024 conv=fsync filefrag test test: 10 extents found, perfection would be 9 extents When I create the file in the same dir, but from another machine, mounted over NFS: filefrag test test: 4833 extents found, perfection would be

So, I have a test domain set up with rfc2307 = yes . Now I'm trying to figure out if a) my nfs automount data came over from OpenLDAP, and b) if not, how to get it into samba 4's ldap, or something else??? Do I need to rethink my approach? Mount locations are pretty consistent based on primary group/userid Needs to work on Linux. Existing entries look like this... # /u,

Our large and complex build system is having very sporadic failurs as we try to update to CentOS 4.5. This takes the form of files that exist - and have existed for some time - not being found: file.whatever: No such file: No such file or directory This happens both with source files, .o's - meaning that the errors come from both the compiler and linker. The build storage is on NFS and the

I set up a 3.3 gluster volume for another sysadmin and he has added it to his cluster via automount. It seems to work initially but after some time (days) he is now regularly seeing this warning: "Too many levels of symbolic links" $ df: `/share/gl': Too many levels of symbolic links when he tries to traverse the mounted filesystems. I've been using gluster with static mounts

Hi, I hit a bizare problem with dovecot 2.2.7 on debian 9 with LMTP enabled and auth/penalty disabled as documented here : https://wiki.dovecot.org/Authentication/Penalty Use case : I run a swaks command to send an email to an exim4 that tries to make a callout to dovecot-lmtp.

hi, guys: Today when i typed "mount " command on the server and found this message: .. ... 192.168.9.252: /home/share/tmp on /net/tmp/share type nfs ( rw, bg, soft,rsize=8192,wsize=8192,addr=192.168.9.252) 192.168.9.252: /home/share/tmp on /net/tmp/share type nfs ( rw, bg, soft,rsize=8192,wsize=8192,addr=192.168.9.252) 192.168.9.252: /home/share/tmp on /net/tmp/share type nfs (

We are seeing some poor performance recently that is focused around users with large mailboxes (100,000 message /INBOX, 80,000 message subfolders, etc). The performance problem manifests as very high system% utilization - basically iowait for NFS. There are two imap servers with plenty of horsepower/memory/etc. They are connected to a 3050c cluster via gig-e. Here are the mount options:

Peter, we found that nfs over udp will corrupt data under very extrem load, there is no way to fix it due to the way how UDP works. TCP will not have these problems. I also wonder why the package size is only 1k. Everyone who wishes a slow connection can pass the desired options via the kernel cmdline. Everyone else prefers probably the fast mount. The defaults should look more like that: ---

Hello. We have a number of Xen 3.4.2. boxes which have constant iowaits at around 10% with spikes up to 100% when accessing data over NFS. We have been unable to nail down the issue. Any advice?

Background: I'm new to dovecot (although with many years Washington IMAP behind me). We're considering migrating from Washington IMAP to dovecot on the main service here, and have just started trying dovecot, using RC7. Washington, IMAP has the usual(-ish) "/var/spool/mail" shared area for the INBOX (trad. UNIX "From " format); a user's folders default to being

Hi we have samba 3.0.14a on FreeBSD 5.4. We tried with different kind of locking and oplocks (both enabled and disabled). If we try to copy from a Windows XP client a file larger than 3g, we get these error: Cannot copy XXX. The specified network name is no longer available.

Sorry for the delayed response, Louis, I'm not sure how to tell about having "cifs/UPN" - Please advise. I was able to mount with sec=krb5 after the user is logged in but that does not help getting "home" mounted during the login. But here is where I am now: I have been able to pam_mount "home" during the login but could not get the ACLs during the mount
