similar to: Ext2/3 fs and defragmentationn

Hi, first of all, apologies if this isn't the right mailing list but it was the best I could find. If you know a better mailing list, please tell me. Today I tried to defrag one of my filesystems. It's a 3.5T large filesystem that has 6 software-raids in the bottom and then merged together using lvm. I was running ext3 but removed the journal flag with thor:~# tune2fs -O ^has_journal

Hello everybody, reading about the speed improvements possible with (on boot) preloaded files (which should be continuous on disk) I searched for a ext3 defrag program. I found an ext2 defrag program (http://www.ibiblio.org/pub/Linux/system/filesystems/defrag-0.70.tar.gz, available in debian as defrag) which would have an optimal feature (moving files by a list) but refuses to work on ext3.

I have just been thru rebuilding a server that had been suffering severe performance problems. I transferred the partitions to another hard drive, copying into freshly formatted filesystems. This made a HUGE difference in performance. One key directory structure stores email messages in an structure where there is a directory for each mail account, and the messages are stored in

I have made some more research and found out the following .. thor:~# df -i Filesystem Inodes IUsed IFree IUse% Mounted on -[cut]- /dev/mapper/vgraid-data 475987968 227652 475760316 1% /data thor:~# strace e2defrag -r /dev/vgraid/data -[cut]- mmap2(NULL, 1903955968, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x46512000 (delay 15 seconds

Hi all, When I do a simple string search with Yum (ex. yum search *hwinfo*) my laptop suffers high slowness. If I open another shell-tab and execute top command, it shows me an extensive use of hardware resources from Yum (20-25% RAM and 70-85% CPU). If in the same time I'm using Firefox browser the performance goes down too much and even it seems the box it's freezed. The box become

Hi all, I'm setting up a CentOS 4 in AMD64 box. The goal is to mount a terminal server with LTSP software. Currenlty I'm in troubles with the multimedia support. I've added Dag's, Karanbir's and Dries' repositories according that. ?Is there some intention to make a multimedia group as others groups (FTP Server, Web Server... etc)? It would be great. ?What packages do you

Hi all, Recently I've suffered a problem with my SMTP service provider. It seems the SMTP server allows open relay, so my account is lockdown by CentOS list policy. Because of that I desubscribe my last account and re-subscribe in CentOS list with the present gmail account. I can send any messages in the list, but the curious problem is I don't see my own messages ???? I can see my

Hello, Today I was working with MySQL in a test box (CentOS 5.0 x86_64) using phpMyAdmin interface.

Hello Gurus, Greetings. I have been assigned some work on the development of a migration tool. The requirement is that it has to migrate the data on a UFS/VxFs filesystem to an ext2 filesystem. What are the technical apects I will have to look into to achieve the same? Is it possible to change the on-disk structure of the UFS/VxFs filesystem to an ext2 filesystem? The question may

If you are using XFS - there is mount option "discard|nodiscard" From XFS man page: discard|nodiscard Enable/disable the issuing of commands to let the block device reclaim space freed by the filesystem. This is useful for SSD devices, thinly provisioned LUNs and virtual machine images, but may have a performance impact. Note: It is currently

Hi, Recently I've got several errors in one of my backups systems. The backup system uses basic tools: rsync, mysqldump, and zip and have worked fine until a few days ago. The zip command shows an error like this: size limit exceeded. So I've found out an alernative : p7zip. It seems to has all the needed features: * available package (in Dag's repo) * 64 bits for size
