when i run the command "bonnie -d /home/disk1 -s 100" it tells me "You must use the "-u" switch when running as root." but if i do it does nothing :\

Look carefully at what the usage message is telling you, especially for the -u option. It requires an argument, and your command line has none. Supply the argument, or don't run it as root.

but again i don't know what "uid-to-use:gid-to-use" means :\

Have you considered using tar.gz files instead?

You will save quite a lot of cpu power. rar, in terms of cpu, is like bz2: an authentic hog. The compression ratio is better than this of gzip, though.

user id (UID) and group id (GID) or a non-root user. Why are you running as root?

help please?

Mr. C. · 09-28-2008, 02:21 PM

Steve,

Bonnie++ crashed. The first error we see is:

Can't open file ./Bonnie.625.000

which indicates that it cannot open the file in the current directory. The current directory permissions are probably not writable to the non-root user you are logged in as. Change the directory permissions or ownership so that you can write to the directory.

Once fixed, if this doesn't resolve the crash, did you install via some pre-packaged binary, or compile from source? I can't tell from the crash if this is a bonnie++ coding error in dealing with an non-writable directory situation, or if this is a problem with an incompatible binary version of bonnie++ being used on your system.
