Is ext4 stable on CentOS 5.5 64bit? I have an email server with a great deal of disk i/o and was wandering if ext4 would be better then ext3 for it?

Hello all, I've been on a real roller coaster ride getting a large virtual host up and running. One troublesome thing I've discovered (the hard way) is that the drivers for Marvell SAS/SATA chips still have a few problems. After Googling around quite a bit, I see a significant number of others have had similar issues, especially evident in the Ubuntu forums but also for a few

We tried to migrate from old Windows fileserver (p4, single HDD) to Samba (FedoraCore15, Samba 3.5.12-72.fc15, ext4 volume, xeon, raid5). Our pipeline is so, that some special software generates files on that fileserver. The typical filesize ~50 mbytes. On the old hardware, software (win2k3 server) the time of single file creation was about 10 seconds. On the new configuration it takes 20-25

Hi, I tried performing a complete copy of 17GB of filesystems over the WAN (0.8GB/hr) with the speed of 16Mbps. The filesystem consists of several large g-zipped files. These large g-zipped files have actually been zipped out of other sub-filesystems and directories. I noticed that while transferring a lists of large g-zipped files, rsync tends to take a much longer time to transfer those files

Hi, I'm using PXELinux latest (6.03) and I encountered a very strange issue. I've converted a CentOS Live ISO to PXE, and I'm using lpxelinux.0 to boot it. Without any HTTP method in the lines, the files are transferring without any problems, but as soon as I use http, all the transferring action is super slow - 5-8 times slower compared to stanard TFTP/UDP transfer (with the same

Greetings! I am currently building a PXE distro server for a company that I'm contracting for, but I'm having some problems. Here's the scoop: Some of the clients I want to install on are Angstrom blades with Intel e1000 NICs. Using the pxelinux.0 file on the FC6 distro, I can install FC6 just fine. However, FC4 bombs. The system pulls it's DHCP address just fine, and then

This is a followup to a recent post on using atop() to obtain multiline expressions. My reading of the plotmath docs makes it clear that issuing (in base graphics) the specification par(cex = 2) doubles symbols and regular text in subsequent plotmath expressions. However, it is unclear to me what specifying cex _within_ the annotation function using plotmath should do, and the following seems

There is one simple change that appears to shrink linked bitcode files by about 15% Whenever anyone proposes a custom compression scheme for a data format, the first question that should always be asked is how does it compare to using a generic off-the-shelf compression algorithm.

Hi, I''ve been using btrfs for my root partition for about a month on archlinux and recently Ive started using the i3 window manager and starting X manually and I now boot to run level 3 (multi-user.target for systemd) and Ive noticed that booting archlinux on a btrfs root, there is a lot off hdd chatter after the login prompts are displayed, which doesnt happen with ext4 on root, so I

Hi, I've observed that dovecot doesn't displays all mails from compressed via gzip mailbox (mbox). At the same time "mutt -f mailbox.gz" displays it correctly with all messages. I'm using archivemail to archive old mails. Internally it creates new "gzip" archive with "expired" messages and then concatenates it with archive. The easiest way to reproduce

Hi, I have btrfs volume, shared via samba. I have a directory of documents that I want to backup on my server. win7 reports a maximum of ~3.10MB/s transfer transferring the same directory on a ext4 samba share I get 25MB/s + Any ideas? Is it like that because of how btrfs works and is setup? Thanks, -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body

Hi all. I have a large data set on solaris 2.6 (approx 16gb and about 900K files and rectory structures). Rsync is misbehaving in the most obnoxious way: it is launched as such: rsync -e ssh -aLv --bwlimit=512 --timeout=300 <source> <dest> A transfer starts, a list of files and directories is built, and data starts flowing. then for no apparent reason data stops flowing form the
