Re: Why syslog is not rotating?



Raco already basically said what the issue is. I didn't notice it in
the prior messages you posted. If you wanted to confirm, after you
migrate your data, do a:
dd if=/dev/zero of=<old disk>
and then looking at something like:
iostat -xtc 5 /dev/<old disk>

And, if you don't see an error there, do
dd if=<(tr '\000' '\377' < /dev/zero) of=<old disk>
and look at the iostat for that.

Even if the disk won't tell the kernel it's breaking, chances are dd
will error. But, even if that doesn't happen, you'd notice a big slow
down with iostat.

As it is, disks are cheap - get another one and be done with the old one.
