|
|
I'm going to make slow network storage powered by gentoo.
it will be made of SATA disks in linux software RAID5 or 6.
it will be accessed through couple of linux software iSCSI targets and NFS servers hosted on multiple 1Gbps NICs.
guess that single storage partiton would be about 10TB large.
and, here I have a question: which filesystem to use?
ability to grow filesystem after expanding RAID would be a must.
ability to shrink filesystem would be nice, but not mandatory.
performance are welcome, but reliability is more important.
any advice about filesystem?
any advice about anything else? _________________ gentoo user |

if you want reliability id go ext3, its very mature and stable. _________________ “Music is a moral law.

xfs is expandable but not shrinkable, and you should use xfs ONLY if you have very, VERY reliable UPS !!!
lvm ?
Currently I'm using reiser4 on my raid10 (lost data few times with xfs - power outage and my ups did not come on line fast enough) _________________ "Dear Enemy: may the Lord hate you and all your kind, may you be turned orange in hue, and may your head fall off at an awkward moment."

I have APC SmartUPS SUA750I and had no problems so far using XFS, but it was not RAID and it was not so big partition.
ext3 is the most mature and stable.
how about ext4?
it's quite new, but considering it's in stable kernel tree now, guess it will stabilize quite fast...
I would skip reiser4 because I don't need such a level of performance and I would like something more supported/tested.
I would skip reiserfs because I've read it doesn't scale too well with parallel request/processing/disk access.
about LVM, I don't know what could I get from it. I have RAID5/6 expansion with linux kernel RAID and I don't need snapshoting.
any other adventage of LVM? _________________ gentoo user |
