<1> pfft
<2> what's the number of directories that can exist in a single directory before you start running into performance problems with ext3?
<2> 2.4 kernel
<1> nonexpend: thats a good one for a google .. i dont think anyone could throw that up offhand
<2> i'm searching but not finding my answer :( so i came here :)
<1> :))
<1> default number of inodes is given by V/2^13, and the minimum by V/2^23.
<1> where V = volume size
<2> that would only be for how many of them i can exist.. i'm looking for a ball park number that i shouldn't go past due to performance problems
<2> them can exist
<1> yeah im lookin ;)
<1> nonexpend: .. ok
<1> from what im seeing... it works like this.. a dir is treated just like any other file, thus the restriction is the maximum single file size
<2> ~2GB on 32bit
<1> yeah .. so basically as many entries as you can fit into 2Gb
<1> but how many that is .. :x
<2> that's the hard limit though
<2> when do i start running into performance problems? ~2000 directories?
<1> yes it is
<1> nonexpend: at my work.. we have a maildir .. its got around 10,000 directories
<1> we have no issues
<1> thats ext3
<1> nonexpend: im seeing another here claim 20,000 no issues
<1> "I think that this limit will not ever be a practical limitation. Other problems will become important long before this limit is reached."
<1> nonexpend: .. ah!
<1> EXT2_LINK_MAX=32000 ...
<1> thats the number of links that will be handled under a directory
<1> with ext2
<1> id say with journalling and such.. ext3 will outstrip that
<1> two seconds ill grep my linux source for the EXT3 max..
<1> nonexpend: #define EXT3_LINK_MAX 32000
<1> its the same
<1> so you can have 32,000 links..
<1> ./include/linux/ext3_fs.h in here if you are interested
<1> ill bet you can handle 32,000 without issue
<1> MINIX_LINK_MAX 250 hehe
<1> UFS_LINK_MAX 32000
<1> MAX_US_INT 0xffff --> REISERFS_LINK_MAX (MAX_US_INT - 1000)
<1> nonexpend: http://www.kerneltraffic.org/kernel-traffic/kt20010514_118.html#4 an explanation
<1> ok tahts it
<1> im out
<2> thanks znx
<3> Tweety_01:.0 VGA compatible controller: nVidia Corporation NV28 [GeForce4 Ti 4200 Go AGP 8x] (rev a1)
<3> anyone get a dualhead working on one of those ?
<4> cp * /home/mosborne/www/images/ -> bash: /bin/cp: Argument list too long
<4> How do I copy all of the files... if it says it's too many?
<5> I need some ***istance in enabling my usb in the kernel I think. I compiled a new one, and now the usb mouse doesnt work. I cant see why it isnt working.
