I'm using 50GB of that for Windows (kid games :-)) and 10GB for Linux, have formatted it as EXT2 but now I'm thinking of trying one of the journaled file systems, reiserfs or IBM's JFS or EXT3. I haven't used that new partition yet. My Slackware system is EXT2 on the original HD. I work in AIX support at IBM (systems performance, mainly) and I'm thinking this will be a good opportunity to learn more about the LVM at home. Is there one of these journaled file systems that you all would recommend over the other? I'm not sure how I'm going to convert to the new filesystem, although I should be able to make the filesystem on the new HD whatever I want, so I'm halfway there.

I don't think any of them are 'the best'. ext3 seems to be the most solid from what I read, but not great for performance. reiserfs is great for lots of small files. It was tuned for news servers. xfs is great at delivering streaming video. I don't know anything about jfs. I chose xfs 2 years ago as my filesystem of choice because I assumed it would be the most rock solid due to the SGI support. That has not been true, but the current XFS 1.3.1 seems to work pretty well. Maybe there is a wiki somewhere that talks about the pros and cons. If not, there really should be.

There is, I've seen it, but I've lost the url. IIRC, the "pro" for jfs was that it had the lowest CPU usage. If you want to tinker with logical volumes and journaled file systems to learn more about AIX, I'd go with jfs. I believe it's related but not identical to the jfs in AIX. I've used both AIX and Linux, and like both. There are some interesting differences in their LVM, but in general your idea is sound. I'd recommend you try all of the file systems and compare them yourself. -David ^ permalink raw reply [flat|nested] 10+ messages in thread

With Ext3 you can grow the filesystem offline and with a kernel patch you can grow online, you can not shrink. Reiserfs V3 you can grow the filesystem online and skrink offline. I do not know the capabilities of the ReiserFS V4 (you need to patch the kernel if you want to test Reiserfs V4) . Xfs you can grow the filesystem online, no shrink. Jfs you can grow offline (probably there is a patch for online growing), no shrink. With the last version of lilo and grub you can boot all these filesystems with the LVM (probably grub need a patch to support the boot form a logical volume). Best regards.

You can only use one on a given logical volume (aka partition), but you can, for example, use ext3 for /, ext2 for /usr, Reiserfs for /var, xfs for /opt, and jfs for /home. I wouldn't do this on a heavily loaded production server, but on a test system there's no reason at all you can't do this. -- David Johnston <david@littlebald.com> Little Bald Consulting, LLC ^ permalink raw reply [flat|nested] 10+ messages in thread

This is not true. Using resize2fs you can grow and shrink the filesystem, but only offline. I'm not sure about the kernel-patch, but I'm certainly sure you can shrink at least offline. And using e2fsadm in conjunction with lvm is even more comfortable ;)) Although it had some issues with ext3, as sometimes a filesystem is reported unchecked even if you have run an e2fsck -f just right before. But adding a -f to resize2fs has always worked for me without any trouble at all. I chose ext3 2 1/2 years ago, when doing kernel development for my diploma thesis, and an occassional ooops or other crash happened almost regularily. And waiting for the filesystem check annoyed me after the 3rd time ;) The argument for ext3 at this moment was, that you can easily convert an ext2 filesystem to an ext3 filesystem using tune2fs -j (to add the journal), and even mount the ext3 filesystem as ext2, making it available even if you have no support for ext3 in your kernel (2 1/2 years ago quite important!) Ext3 has never failed me in this time, I had no failure of filesystem and the performance was also good, at least for my needs :) CU all, Jens -- GPG: 1024D/CF884D50 F2E8 F7FC F823 6464 4E9D EFAB 6EE9 8B9C CF88 4D50 ------------------------------------------------------------------------ Jens Hoffrichter / joho@hausboot.org / Joho@IRC / Fon: +43-650-5376989 The color of nature is not green.
