slackware 13 - sluggish system (possibly filesystem)
 

Hello

I've installed 13.0 on a Dell PowerEdge 2650 and upgraded all
installed packages using slackpkg. The system is extremely sluggish,
particularly filesystem access, it seems. For example, trying to
create a database in PostgreSQL takes forever (PostgreSQL is simply
copying files into a new directory).

This is the second time I've installed on this server from scratch; running fdisk on all the partitions revealed no issues.

Could anyone suggest how to get to the root of the problem?

System info:

The hardware RAID array has two disks in RAID1 configuration.

Thanks
Dale

I've pasted the output of the following to Pastie:

strace vim /etc/rc.d/rc.M

Pastie URL:

http://pastie.org/987150

Is there anyone on this forum who understands where to find issues within the output? This may give someone insight into why the system is so slow. vim takes a long time to display the files I ask it to edit.

I'm particularly interested in the lines from line 780:

select(1, [0], NULL, [0], {0, 0}) = 0 (Timeout)

Could these indicate the general overall system delays I'm experiencing?

Hello zoot
what filesystem did you use?
ext4? or what?

Yes, ext4. Never used it before, but noticed that it's the default for Slackware and Ubuntu now, so must be stable???

All the system info is here:

Thanks

The OP uses ext4.

edit: being too slow

What about RAM? Can you post free -m

I admit I haven't yet used ext4 on any of my systems...
sycamorex; would/could the fs have anything to do with it?...probably not

I wonder if hdparm will work, try running it:

Never tried this with RAID, but it should work on each HDD.

Also, what kind of RAID is this ? software/hardware

What kind of drives are they SATA, IDE ? From the info you posted it might be PATA ?

The filesystem can have something to do with it, so that would be one thing to try (like XFS, JFS, or others), but first answer the above.
