Hi,
Sure. Camcontrol does indeed cover IDE, SCSI and SAS drives.
Replace this line:
On FreeBSD, IDE drives can be queried using atacontrol...
With this:
On FreeBSD, IDE drives can be queried using camcontrol identify...
In other words, the query is the same as for SCSI drives. For verification this is what the output looks like:
root@bsd11desk:/home/jre # camcontrol identify 0:0:0 | egrep "Feature|write cache"
Feature Support Enabled Value Vendor
write cache yes yes
I appreciate the Postgresql docs are not meant to be FreeBSD tutorials.
Thanks,
J.
