Hi,
I have a problem with a Dell Poweredge SC440 computer.
It's equipped with a "Dell SATA/SAS 5iR" controller, it's from
LSI actually
(maybe megaraid).
I'm using FreeBSD 7.1 Release
I have 2x 500 GB SATA in a synchronised(status optimal) RAID-1 logical
volume.
The machine is brand new, first problem arised early after the installer
started to install the files, the install was very slow, (I know it is
because write cache is not enabled, that can be done with a management
program, and I will enable it later) and sysinstall could not install the
ports collection, the error it gave was
"write error on transfer to cpio process, try of 1024 bytes" after
OK,
write error popped up.
I found this error too, but I found no clue what could have happened.
Installing the system without the ports collection (installed it later with
cvsup)in another run gave no error at all, and in dmesg is see the logical
volume:
mpt0:vol0(mpt0:0:0): Settings ( Hot-Plug-Spares High-Priority-ReSync )

da0: 476837MB (976562176 512 byte sectors: 255H 63S/T 60788C)
It looks OK, but then I found this after typing "df -h", and it gives
me the
creeps:
Filesystem Size Used Avail Capacity Mounted on
/dev/da0s1a 496M 138M 318M 30% /

/dev/da0s1f 440G 537M 404G 0% /usr
/dev/da0s1d 2.9G 1.3M 2.7G 0% /var
I'm reading the freebsd-current list, and I found another buffer related
problem there, but they say nothing about these.
If you have any explanation/solution for these problems pls share them!

The used/available inconsistencies are due to space being reserved. Regarding disk performance, you need to put hw.mpt.enable_sata_wc=1 in /boot/loader.conf to reenable the write cache (it's disabled by default for consistency reasons when using SATA disks leading to poor write performance).

Just another thing, can you change or monitor the behaviour of this spare space reservation? Looking into man mpt gave nothing useful regarding this issue. Adding hw.mpt.enable_sata_wc to the loader conf made everything much faster, before that the computer used the disks all the time. Thank you for your help Richard, Best Regards, B.
