it's sad to see...

@MechMK1 I've been going with ZFS these days but ext4 is fine

btrfs

I'll just leave this here...

The Winterbash countdown annoys me. Both digits of the seconds flash even when the left one isn't changing.

is it that time of the year again?

How else would we know it's christmas, if it were not for hats?

I've never been a hat's guy...

I mean hats are silly and stupid, but so am I.

good point

another Brazilian thing today... our constitution says the leaders of the congress and senate have 2 year terms, and cannot be reelected. but the current leaders appealed to the supreme court, and the supreme court is voting, but it's 4 to 2 to allow the reelection, but asking them to not hold more than 4 terms

if the constitution says it's forbidden, not allowed, prohibited, and they went thru with the reelection, would a "politician promise" stop them for holding office forever?

trickbot now can write UEFI implants and survive system wipe... scary...

So

New HDDs arrived

Checking the first one for bad blocks now

70 hours!?

Fuck that, m8

What's the best tool for copying all data from one directory to another while still showing progress and being disaster-safe?

Context: My old hdd is mounted to /media/primary and my new hdd to /media/secondary

And I doubt cp -r would be the wisest choice

screen sudo rsync --progress -ah /media/primary /media/secondary

cp from coreutils 8.32 onwards have a --progress-bar switch

Why did I have 130 MB/s xfr and now only 1.3 MB?

My iowait is 50%

are you copying to usb drive?

the 130mbps at first was copying from the drive to the cache, and once the cache is full, the real bandwidth is that 1.3mps

dd if=/dev/zero of=/where/you/mounted/the/device bs=1M count=256 oflag=direct will skip the cache and write direct to the device, so you can know how fast (or not) the device really is

I don't get it

At times it's at 60MB/s

Then down to 1 MB

Then at 90

cache...

there's space on the cache? the read bandwidth is the bottleneck... cache full? empty the cache at slow speed to the destination device... wow, cache empty again!

test the speed with dd...
