 Posted: Thu Dec 02, 2004 5:17 pm Post subject: Do i need to configure XFS? |
 |
|
Hi everyone, especially the XFS users!
I am going to make XFS my new filesystem. I read some post which told that XFS needs to be configured to really work fast. Is that true?
I was going to just do:
| Code: | | # makefs.xfs /dev/hda10 |
Do I need further options or is it enough? The partition will be about 108GB.
| Code: | | # makefs.xfs --help |
gives me the following
| Code: | Usage: mkfs.xfs
/* blocksize */ [-b log=n|size=num]
/* data subvol */ [-d agcount=n,agsize=n,file,name=xxx,size=num,
(sunit=value,swidth=value|su=num,sw=num),
sectlog=n|sectsize=num,unwritten=0|1]
/* inode size */ [-i log=n|perblock=n|size=num,maxpct=n]
/* log subvol */ [-l agnum=n,internal,size=num,logdev=xxx,version=n
sunit=value|su=num,sectlog=n|sectsize=num]
/* label */ [-L label (maximum 12 characters)]
/* naming */ [-n log=n|size=num,version=n]
/* prototype file */ [-p fname]
/* quiet */ [-q]
/* realtime subvol */ [-r extsize=num,size=num,rtdev=xxx]
/* sectorsize */ [-s log=n|size=num]
/* version */ [-V]
devicename
<devicename> is required unless -d name=xxx is given.
<num> is xxx (bytes), xxxs (sectors), xxxb (fs blocks), xxxk (xxx KiB),
xxxm (xxx MiB), xxxg (xxx GiB), xxxt (xxx TiB) or xxxp (xxx PiB).
<value> is xxx (512 byte blocks).

I've used XFS without configuring it with any special parameters. I guess if you're fanatical about performance there are a number of things you can do to tune it beyond the defaults. For that, your best bet is to read the XFS docs. Also, there's sys-fs/xfsprogs, but I'm not sure how many of those are designed for performance tuning. If you just want to get up and running, the defaults should be fine.

| Do you have any idea how much this tuning speeds up the fs? If tuning improves performance less then 3% then I wont bother. |
