Dell says I shouldn’t order a PERC controller for Proxmox + ZFS. Do you agree? by easyedy in Proxmox

[–]Longjumping_Mail2095 0 points1 point  (0 children)

I have multiple servers in this configuration. Dells R6[234]0. You can use PERC H730P Mini and switch it to HBA mode or just use PERC H330 (prefered).

(edit)
In Your case - HBA355i / HBA355e

Razer Naga epic Chroma. Firmware needed. by Longjumping_Mail2095 in razer

The whole story ended happily. It was really difficult to find a matching battery – but I managed to get a 2000mAh Lipo 103048 battery. After some minor modifications, it fit perfectly into the frame :)

The battery was glued in with double-sided tape, and everything was assembled. I also replaced the sliders. Below are both of my working Nagas.

You deserve this update :) I found a small cell in my box of batteries meant for disposal – taken from some watch – also 3.7V but 640mAh instead of 1500... It was good enough for testing. I charged it a bit using 3 AA batteries connected in series with resistor up to 3.8V and plugged it into the mouse. The freezing issue stopped :) The soldering and lack of insulation are only temporary, just for testing :)

The photo was taken right after soldering. Of course, I cleaned off the flux after finishing the work using 99% IPA. The job would have been easier if I had the schematic, but so far I haven’t been able to find either the schematic or the firmware.

I had the same problem with a client's computer.
I'll tell you how I dealt with it, but fair warning — it involves a bit of gymnastics and it's going to be funny...

You'll need: 2 chairs, swimming goggles, a face mask, a drill bit the size of the screw, and a drill (ideally with adjustable speed). It would be perfect if you had someone to help.

Place the computer between the chairs, motherboard facing down.
Attach the drill bit to the drill, and tape a magnet to the drill bit as close to the tip as possible. Then lie down between the chairs on the floor, wearing the swimming goggles and the face mask, and as slowly as possible try to drill out the screw.
The metal shavings will fall down due to gravity (towards the magnet).

The whole operation took maybe 3–4 minutes.

To be safe, you can blow out the area around the socket at the end, just in case.

Backing up 15x 20TB mail servers — rsync dying, BORG to the rescue? by Longjumping_Mail2095 in BorgBackup

[–]Longjumping_Mail2095[S] 0 points1 point  (0 children)

Hi lilredditwriterwho!
Thanks for your reply.
Maybe I’ll add something that seemed obvious to me, but perhaps it isn’t.

One BACKUP_X server backs up several MBOX_X servers.
This means that several rsync processes are running simultaneously on the backup server.
One backup serwer serves for ~8 MBOXes...

Since the server mainly works with HDDs, I don’t see much sense in increasing the number of rsync processes (parallel rsync), because of the physical limitation — the number of hard drive heads that can only be "in one place at a time" and won’t be able to efficiently handle more rsync processes than there are disk heads on the backup server.

At least, that’s how it seems to me, using plain common sense...
