Hi,
we are building a small disk array in our studio and I would like to ask what would be the best setup to use.
We did some benchmarks, but we have all but the time to tweak & test all filesystems/parameters.

So, my question would be if anyone here has experience with similar setup. (9 x 1.5TB hdd)
Primary task for the array is shared storage for video files (20-30gb each).
So far, we have been using 7 x 1.5TB and ext3, which has become quite laggy over time (creating directory takes more than 20 seconds if the utilization of array is above 80%). We used raw raid5+ext3, no lvm.

Do you think the setup mentioned in subject is ok, and if so, what parameters to use for xfs?

thanks for any suggestions

what do you suggest then?

thank you all for explanation about pros and cons of the alternative.
I'm thinking about leaving current setup: 7 disks in raid5 with ext3 as it is and buying one more disk, so I can build another array with xfs on top of lvm on top of raid5 on top of 3 disks.
And over time, I'll try to migrate stuff from old array to new one with simultaneously extending it.
Maybe one last question, what xfs tweaks do you suggest (chunk size, log size, ...)?




there is always some project going on. we have never been in state [idle] as far as i can remember.


well, the thing is i cannot hit pause for a few days if i could I wouldn't be asking for help here.
