Update On New DIY JBOD

Before I give an update, I want to say that it may be cheaper to buy a purpose built case, I am doing three of these so I got a little bit of that economy of scale going for me. When done I will do a BOM on all this and we can compare.

Why three?

Replacing this monstrosity

Yes that is a Samsung SSD hanging by the friction of the connectors.

And recall this post? https://www.apolonio.com/blog/?p=12520

Here is an updated picture with 16 x 4TB drives

So that is actually two units but considering it one.

Then here is the first one.

Still a few more things to print. On the back interface and HBA it is almost ready

Got the wrong brass inserts though, they are too big, and the ones I had on hand were too small.

Anyway it is coming along, predict it will be done by end of Sunday, maybe not in production but production ready.

Keep getting problems with drive alignment. Had to a custom one with a drive a did a block check.

When I did a pvcreate I had to do this

pvcreate --dataalignment 1m /dev/sdc1

Went swimming today, got a lot done too. Feeling good. But it is late.

I didn’t display it but my lowest weight since I was recording was the data Toto passed, it was 322.4, the next day I was 322.6 I am a pound away at beating those numbers. It is possible to crack 320 by end of Month and an outside chance of cracking 310 by end of year.

Been Over A Month

Been over a month since Toto left us.

The healing continues though, but seems to moving too slow.

I touched his memorial today, reminded me of him being around.

Life is quiet, not ready for a new dog… yet.

Almost got one last week.

On the daily notes, Seahawks lost, got a bunch cleaned up at home. Got new rack going.

Keeping busy, getting ready for next dog.

A New Office Chair

I spend hours in this chair I am sitting in. It is not unusual for me to be in my chair for 12 hours in a day. So I looked at some high end chairs

The chair which looks like a gaming chair is over 4k. But I admit it is comfortable. Can’t do it. Too expensive.

  • Got a lot of things done today, prior to looking at the chair I continued with fixing failing drives.
  • After the chair, went to try woods coffee for the first time, one of the better coffees I have tried.
  • Then went to Costco again cause one of my son’s needed to restock.
  • After Costco went to get Mexican Fried Ice Cream for my other sone.
  • Then went to Lowes to get a new leaf blower for my wife.

Finally got home at about 5:30PM and I tried to get my new JBOD going, but the inserts I got was too small.

I pivoted and got most of my physical drives monitored on my network. Noticed more heat. Heat is the issue.

Haven’t mentioned it but the days I did not swim I did not do 10k steps. Too cold.

Replacing Failed Hard Drives

Got a bunch drives that a needed to replace, kind of a pain. I finished one on my media center, and my backup server. It was a lot of work to get in to.

I did swim today, got a lot done in the evening, went swim, got meds, got food, picked up my amazon.

Lot of things to do this weekend.

My JBOD server is coming around too.

Health Of Hard Drives

Last night I had a scare, one of the archive checksums did not match up.

Luckily got backups and it was discovered while I was replacing the hard drives.

One thing I been on lately is checking on the health of my hard drives. I can’t do much for the ESXi hosts, but I can do for the physical hosts especially the linux ones.

I found a couple of bad drives, one in my media center and another one in my filer.

Heat is also an issue so I am putting in monitors for all of that.

Finally, I have not been backing up my desktop since I got it, no drive space left.

I have ordered a couple of hard drives, one to replace the bad drive in my filer another to add media capacity, and finally one to backup my data.

Accidental JBOD

This JBOD backplane came in yesterday from aliexpress. I didn’t have plans for it but it was cheap and was worth a look. Turned out to burn a hole in my wallet.

Has huge promise, got a few things to test it out. Hoping to get it rack mounted this weekend.

Oh yeah need a new rack now.

Looks like this kicks of my 2026 network reorg plans.

Repeating Blog Post Titles

Was about to title this Cleaning Up Network, yesterday I was going to post it as back to swim. I am starting to notice I have so many posts, the titles are getting reused.

Anyway, I am cleaning up my network, something low effort I can do. One thing I started today was to clean up my influxdb telegraf database. As I post it is currently backing up. Should be done tomorrow morning and I can remove some older records.

The database needs some serious cleaning up.

No workout today, felt weak and tired all day.

Back To Swimming Routine

Back in the pool today, got to admit, I was kind of off, almost was late, forgot my locker combination, almost forgot my swimming headphones, had to think about what I needed.

Also to add to the confusion it was cold.

Went to OT today, convinced to get a new chair, looks like my arms need to be higher.

Figured out how to use device id instead of device name in nagios. Should make things more reliable.

So instead of using /dev/sda I would use something like /dev/disk/by-id/scsi-SATA_XXXXX

Weight going down though, am tired should sleep well.

Living Room Rack

Here is another rack I just finished. This one services the living room entertainment area.

Note the Rpi on the top, I am considering using one of the blank areas below for it.

As I was building this, I was thinking about redoing my entertainment media both the front end and the back end.

Seahawks won today, my Windows 11 is mostly built.

Windows 11 Rebuilt

I finally rebuilt my desktop, I spent most of the day getting my data backed up and restored.

Ninite is awesome, got a lot of my apps installed quickly.

Remember the launcher from a few days ago, that helped a lot too.

One hiccup was the X520-D2 drivers. Had to hand install that.

Still a lot to go, want to document install what I need.
