No idea whether or not this would be suitable for video editing. Assuming you
I should not have mentioned the video...
already possess the hardware in question, it's only going to cost you the time it takes to set it up and test it to find out if it works well enough for your purposes.
I do not have all the components yet (I do have two candidates for the PC though, one with single PIII about 733MHz and another with dual PIII 800MHz). Regardless of whether the video editing can be possible over this (I currently use Firewire disk), I'm still going to build this. So in time, I will test this.
I have two questions 1) How to set up the disk system? What I'm thinking is that as I have
Check out www.linuxdevcenter.com/pub/a/linux/2006/04/27/managing-disk-space-with-lvm.html for an example of how to move things around in LVM.
This was excellent. I sort of knew all that, but I had only studied what SUSE offers through YaST. Thanks for the pointer.
Is it possible - also in practice - to remove disks from LVM group so that the data is kept on the remaining disks?
Yep. in a nutshell, you'll use pvmove to evacuate the data off of the disk in question, then vgreduce it out of your volume group.
Thanks, so I'll go ahead with the plan of having mirrored disks combined with LVM. Later on, I think I'll change to RAID-5 with SATA-disks, but that's in a couple of years.
Does this depend on the file system? Which file system should I use?
1st part - No. Both MD and LVM2 sit below the filesystem and neither are filesystem-aware. 2nd part - Choose the filesystem that makes the most sense for you. XFS and JFS can both be safely grown online, which is nice. From a "least likely to self-destruct after a power failure" perspective, I've had the best luck with ext3. ext3 can also be grown online with the ext2online program, but be really really careful. If you try to grow it to where it needs a larger block size, it's possible for Bad Things(tm) to happen. Some
I do not know about JFS, I will have to check that out. I've had some experience with XFS at work. Even without any sudden powerlosses and somekind of battery backup on the RAID-controller, I've seen corrupted files (filled with garbage or null). So, I'm hoping to find something else. Ext3 might be good, but I do now like it - even though I can not really say why :-)
people swear by reiserfs. After losing several entire filesystems, I won't trust it. Your call.
I've used reiserfs on my desktops since SuSE 9.1. I've not had any problems, but then again, that doesn't mean that in the case of a problem, reiser could screw up badly... -- HG. -- Check the headers for your unsubscription address For additional commands send e-mail to suse-linux-e-help@suse.com Also check the archives at http://lists.suse.com Please read the FAQs: suse-linux-e-faq@suse.com
