Doing a bit of stress work on a new HDD

As foreshadowed in x8dtu – drive problems, I will be visiting a data center soon to replace a 4TB HDD. The replacement HDD arrived last night. It was unceremoniously tossed onto the front porch by the courier. However, it was properly packaged. I’m sure it’s fine.

Decently packaged drive

The original idea: put this drive into a host, and write some data to it, to exercise it a bit.

As you will soon learn, that is not going to happen.

The new drive

This morning, I added the drive to one remaining empty drive cage of r730-03

After inserting the drive cage into the server, I found this in /var/log/messages:

Jul 10 11:53:27 r730-03 kernel: mrsas0: System PD created target ID: 0x2
Jul 10 11:53:28 r730-03 kernel: da8 at mrsas0 bus 1 scbus1 target 2 lun 0

Jul 10 11:53:28 r730-03 kernel: da8: 3815447MB (7814037168 512 byte sectors)

And now, for some smartctl data (note this was taken about 3 hours after inserting the drive).

I am pleased to see the Power_On_Hours value matches how long I’ve been using it.

It was at this point that I realized my error.

The new HDD was too small. 4TB vs 4.5TB.

Fortunately, the existing zpool is not full:


[12:30 x8dtu dvl ~] % zpool list
NAME        SIZE  ALLOC   FREE  CKPOINT  EXPANDSZ   FRAG    CAP  DEDUP    HEALTH  ALTROOT
main_tank  4.53T  1.26T  3.27T        -         -    26%    27%  1.00x  DEGRADED  -
zroot       212G  56.4G   156G        -         -    50%    26%  1.00x    ONLINE  -

The plan

My plan is to create new zpool using the new drive and name it data.

The first step is to mirror the existing main_tank zpool into the data zpool.

main_tank will be destroyed.

Partition the existing drive to match the new drive.

Add the new drive to the data zpool, creating a mirror.

Wait for the resilver.

The time

Given we have 1.26TB on a 300MB/s connection, it will take at least 1 hour and 10 minutes to copy that data.

Perhaps I’ll try a zfs send< | recv/span> over the internet so the drive at least contains a starting point.

I’ll probably use syncoid for that.

Partition the new drive

The steps in this section are taken from a recent post on creating a standby-spare.

          40  7814037088       - free -  (3.6T)

I record this information for possible future use.

Next, the zfs partition is created.

I know the new drive is going into slot 3 because:
