redhat drive bench? - PC Perspective Forums

Hdparm doesnt work in redhat so is there some equivilent utiltiy or does it use a different syntax or something?

Hdparm -t and -T doesn't work? What kind of disk and controller is it?

Is it some type of RAID? IDE?

SCSI? A good filesystem benchmark (not raw disk performance) is bonnie++.

Http://www.coker.com.au/bonnie++/ It will stress your filesystem to the max, so be careful.

If there are ANY instabilities it will crash the system.

Well this is on a clean install of skipjack on an 8k7a with a single 20gb ibm 60gxp....but i remember a while back when i was running 7.2 i had the same problem...its not that it doesnt work ...the command isnt recognized by bash...gives me that ' command not found ' ....skipjack is pretty nice btw....just ran up2date and installed the new 2.4.18-0.22 kernel...everything running fine except the konqueror amdmb site problem...lol is hdparm part of a package that needs to be installed that isnt by default? thats strange i see it listed as installed when i run the package manager but when i type in at the command prompt hdparm i get that command not found ok so i logged out of kde then looged in as root still in init3 i ran it and it works...wont run in kde as myself or as su to myself...lol...worked in slack so who knows well this is wierd though..i had set up a software raid 0 one partition /dev/hda1 is /boot and then /dev/md0 is / well running hdparm on /dev/md0 gives me a read of 20.8mb/s and when i run it on /dev/hda1 i get 38.1mb/s any suggestions on tweaking the raid0 config....i read from this site an article where they testeda shuttle board i believe and had it pumping out 70mb/s with linux software raid0 config.

I don't have any ideas about software RAID.

Why don't you ask on the Skipjack mailing list? About hdparm and su, your hdparm probably isn't available as a non-root user because it isn't in your path.

Run "su -" to change to root with the PATH variable set to root's path. If it still doesn't work then try "up2date hdparm" which will download and install the package.

Lol...ok and sorry about the raid 0 question...but i thought you handled that very well....LOL....it didnt dawn on me till after i posted the question who i was talking to....but i still would like to see how that guy runnin gentoo linux?

Got 70mb/s uuhhh DUUUUPE....man i feel like homer simpsons retarded nephew....lol...i have a single drive...look at the scores...LOL...ok i'm an idiot....uuuhh can i just take this post back...damn wheres that freakin time machine at when you need it

Linux software RAID 0 is fine.

The dirty word here is ATARAID...

Meaning Promise and High Point's incredibly crappy implementation of RAID. Gentoo is always MUCH faster because every part of it is recompiled on your system for absolute maximum performance.

Your distribution of Red Hat is compiled for i386, meaning greatest compatibility but it wont have any speed enhancements. Gentoo also uses the older 2.95.x gcc compiler that has much better optimizations for high end Pentium and Athlon processors than the newer 2.96.x and 3.x compilers.

Well i am a fickle b*tch cuz redhat is gone and mandrake is in....lol....it installed on my atto ul3d controller redhat and slack wouldnt....so for now i have my 4 scsi cheetahs with a 256mb boot on sda and 256mb swaps on sdb,d,e the rest is / and set up in raid0....now to figure out a bench utility for mandrake...lol...i'm we todd id but its all good if i ever learn enough gentoo sounds really cool
