I tried out reiser4 a while ago, but I found that it was too quirky and became fragmented far too quickly. Good point -- that's a downside I forgot to address with reiser4. Its fantastic, x-better-than-others ok, slightly exaggerated performance will quickly degrade into "a bit better than others, comparable to reiserfs" within two months of heavy usage.
It needs a repacker to stay in tip-top shape, which is nowhere to be found nowadays removed from reiser4 due to stability issues. My choice? Hasn't let me down yet, and I've been managing many many hundreds of TB's using it for a very long time. It's part of the free!! Storage Foundation Basic available here: » www. I don;t know about any technical issues with JFS; I do know because of the sequence of the jounaling in XFS it can result in data loss. No, the mkfs command can NOT be run with data on it.
However, if you are running something like LVM where it's cheap to create another MB partition, you can switch the log to an external device that's the size you desire, without losing data. The latter might get you the best performance. Cabal Premium Member join Good article above too. Should barriers be enabled with storage which has a persistent write cache? Many hardware RAID have a persistent write cache which preserves it across power failure, interface resets, system crashes, etc.
Using write barriers in this instance is not warranted and will in fact lower performance. Therefore, it is recommended to turn off the barrier support and mount the filesystem with "nobarrier". Is it in fact MB already x ?

One thing to notice, they are slighty more relevant to the OP Than, say, random people reading this thread.
The tests were done on a MHz machine which could've posed a significant CPU bottleneck that would cripple reiserfs and reiser4 especially, and maybe XFS to some degree. The setup doesn't nearly reflect the average joe's computer. Ted to jdong Anon Aug am to jdong Wow! Can and I just add here that the addition of write barriers has slowed the performance of XFS down somewhat. GOD you are so right about that!

Joined Nov 29, Messages 9, With my limited experience on file systems I'd say EXT4, because it is the most widely available and used, so you know it gets lot of use and is known to be reliable.
The others often require to have extra stuff installed so only the most advanced people tend to use them. Though there are reasons to go with the others as well, but that's just my personal feeling on it. Not that it means much, but my current main storage at home is 4. Red Squirrel said:.

Its only been in stable e2fstools since like November of last year.

Storage will be added to the raid6 one disk at a time. On another note, are you concerned about silent data corruption? Joined Feb 22, Messages ST3F Limp Gawd.
Joined Oct 19, Messages I have looked at that. However my big reluctance to use zfsonlinux is that this is an out of the mainline kernel driver. I have been burned more than once by these in that after some time development either stops or they decide to follow some other distributions release schedule like RHEL. Joined Dec 13, Messages 2, The reason why probably has to do with ext4's activity. EXT4 itself isn't limited to 16TB, but the program s used to create and resize are. In , the stable version of Ext4 was officially announced and became the official recommended default file system for Linux.
It is the default file system for IRIX version 5. What is journaling file system? A journaling file system has a log which records information about changes made in file system. If file system failures such as a kernel crash or a sudden power failure occur, the system can recover data easily according to the log. This post introduces Linux file system and Linux directory structure.
