Hi all,
Is there a straight-forward way to know if write cache is
enabled on a SCSI disk? I installed 4.2 (both i386 and
amd64) on a ibm x-series 336, and a simple mv of src.tar.gz
from a dir to another in the same filesystem takes more
than 10 seconds.
0m10.49s real 0m0.00s user 0m0.10s system
Thanks a lot.
Best regards,
Josi
ps. below is a dmesg
