With v32 coming soon, I'm looking at an upgrade of not only the software,
but maybe it's time for the 11 year old hardware to be retired. So I'm
looking for thoughts on that.
My current system has an SSD boot drive and 4 SATA II hard drives
configured as 2 mirrors. Since they were SATA II at the time, I thought
that for performance reasons, I needed 2 directories in my Recording
Storage Group so the recordings would be split between mirrors. Not sure
how needed that was, but it's been working well for 10 years or so. A
secondary use of the backend is as a SMB/CIFS NAS for the rest of the house
to use.
Since NAS drives are reasonably priced now, I thought about a pair of
Seagate Ironwolf 4TB SATA III drives used in a mirrored configuration.
So one question is can I forget the use of a second directory in my Default
Storage Group (recordings)? My tuner is a WinTV quadHDTV PCIe card from
Hauppauge and the worst load I have is 4 recordings at a time where there
may be some overlap caused by back to back recordings on the same channel
where the recording rules have extended time at the end.
In the current backend I use ext4 on the boot SSD and the mirrors are set
up as RAID 1 mirrors using mdadm. That works and I've been able to replace
failed drives several times without a problem. However, I've been
researching ZFS and BTRFS and building test systems to play with both.
Since Ubuntu even allows 20.04 to be installed with ZFS, it looks
promising. I really have no idea whether I should go down that path.
I figure that I could probably find a miniITX motherboard with a M.2 nvme
boot socket and then since the WinTV card is low-profile, I could get a
smaller chassis that only holds 2 drives.
Any thoughts would be appreciated.
