128GB mode Failed to Write Slice Error win11 only occurs on SSDs

[BrandtH22]

This issue was reported by Delerium in discord: https://discord.com/channels/1034523881404370984/1102690350218354920/1179030557271793715

Hi guys - im using Win 11 on Bladebit 3.1 with 128GB ram and a 8GB Nvidia RTX 2080 and regardless of setting I keep getting "Failed to write slice on F://p1unsortedx-p11pairs-3lp-p3-lmap.tmp errror 0" - The temp drive is a local 1TB SSD.... what am I doing wrong?

Command used: bladebit_cuda -f xxxx -c xxxx -n 1 --compress 2 cudaplot --disk-128 -t1 F:/ F:/

Notes:

• Issue occurs only when setting an SSD as a temp drive (HDDs work without issue)
• Tried reformatting the SSD (even tried multiple format types)
• Tried using the standalone bladebit and also the integrated bladebit (integrated has error of STDERR: Failed to write slice)
• Tried multiple different SSDs (3 samsung pro evo 1 TB)

I'm nice and active on this Harold-b so if you need me to test alternative settings to root cause this (or experimental releases) please just reach out. (This is the original raiser of the issue - Delerium on Discord).

[harold-b]

Thank you, @GetStreamlined Do you get the same issue w/ the SSD if you use --no-direct-io?

It's a global option that should come somewhere before cudaplot

[GetStreamlined]

@harold-b Sadly same issue. Command used:

bladebit_cuda -f redacted-c redacted -n 1 --compress 5 --no-direct-io cudaplot --disk-128 -t1 F:/ F:/

I also switched the video card to a NVIDIA GeForce GTX 1660 Ti to do more trouble shooting. Sadly same output.

You run Terminal as Admin?

[GetStreamlined]

You run Terminal as Admin?

I did yes and also tried without.

[GetStreamlined]

Additionally tried in powershell (with and without administrator). Same issue.

[teamwest93]

What abot beta1 or rc1 versions?

[GetStreamlined]

What abot beta1 or rc1 versions?

sadly they give a slightly different error (Failed to open plot file with error: 3)

[GetStreamlined]

@harold-b is there any update on this issue - im keen to get plotting as I dont want to go to Gigahorse.

[harold-b]

I wonder if this is related to block size. Would you mind running diskplot on those target SSDs to see what block size bladebit reports (you don't have to make a plot, it should just report the block size for the temp directories).

[GetStreamlined]

@harold-b

Here is the result of the diskplot using the SSD:

If I used the HDD instead its different:

Temp1 block sz : 4096

[harold-b]

Thanks for the info! So it does look like it is block-size related. As a workaround for the time being you can try resetting the SSDs w/ 4k block size while this is resolved

From research on Samsung Pro EVO SSD's you cannot change the block size so looks like I'm stuck waiting for a resolution :(

[GetStreamlined]

Hi @harold-b - hope you had a lovely Xmas and New Year. Do you have a rough timescale of when this will be resolved please?

James

[haorldbchi]

I've started up work on bladebit stuff this week. I don't have a timeframe but hopefully this one won't take much since we know exactly where the issue lies. I certainly haven't forgotten about you

[GetStreamlined]

@harold-b fantastic! If you need me to test a beta release let me know :)

[sonosergio]

I have the same problem ...

[GetStreamlined]

I have the same problem ...

I gave up waiting so I tried Gigahorse. No problem there.

[piotr-nowicki]

Same here. Probably it's better to switch to something else.
