David,
I assume you have the 4 disks in some sort of RAID configuration. If you
want to sweat it, you can pull one drive out and have it re-silver the
replacement drive, repeat for the second drive, etc. If you do this I
would run a scrub before pulling each drive, just in case. If you have
some particularly important stuff I would copy it somewhere.
One other silly thing you might do is to get an external USB enclosure
and use that. You then mirror one of the drives and then shut down and
swap them. If it doesn't work then swap them back. I haven't tried
this so YMMV.
I have an 8-port sata controller but use 6 mirrored pairs (2 internal
and 4 external in a 5-bay chassis) in my setup. This allows me to add
drives to a mirror and remove others with reduced anxiety. The setup is
getting old (It's about 12 years running now) so I'm looking for a
low-cost, low-powered replacement.

Hi all,
I was wondering if anyone had any ideas of what to do for an upgrade?
I have a HP Proliant Microserver N54L with 4x 2Tb drives which I have
been happy with for more than a year but I have started to run out of
disk space in my zfs pool. I have been pruning the snapshots and
rubbish but filling it up now is inevitable.
What I would really like to do is to swap the disks out for larger one
but I doubt that this is really practical as to make this work you
need spare disk slots which I don't have.
Another option might be to add a SATA card and add more disk that way.
But I have no idea of where to start with this, and even if this
microserver can do that.
And a third is just to get a new server. I can't see any which have
more than 4 drive bays do these exist (for reasonable money) or do you
need to make your own? If so anyone got a recommendation?
Thanks
D
