Got my HDDs delivered. How can I test them all before putting real data on them?
Got my HDDs delivered. How can I test them all before putting real data on them?
I got my 10x HDDs delivered from ServerPartDeals, they're Dell branded Exos drives, Seller Refurbished
I know one of the first things I'm supposed to do is make sure they're configured to run at 4K, not 512, so I'll be checking that.
I'll also plug them all into a HDD dock and read the SMART data off them.
Afterwards, I remember reading a guide (here I believe) about how to test all the drives. There was a command line tool to check the drive for errors.
Does anyone know what I'm talking about? I remember I had to run a plugin on the computer to make sure I could run multiple instances of it.
Alternately, I intend to spin up a TrueNAS instance for this, does TrueNAS have any built in tool to fully check the drives before I create any pools?
You're viewing a single thread.
when I get new hdds, i open a tmux instance with one pane per hdd, then i do:
- smartctl -t short /dev/sdX
- smartctl -t conveyance /dev/sdX
- badblocks -b 4096 -ws /dev/sdX
- smartctl -t long /dev/sdX
And if it passes all those, then I put them into a zpool.
edit: for bigger drives, you might need to increase the block size for badblocks, 65535 for example.
2 0 ReplyCan you tell me why you go for 2^12 but then choose (2^16)-1 as an alternative? Wouldn't that create alignment issues?
