| raitobezarius | thankfully I have found another server | 19:54:31 |
| raitobezarius | To me, this is not a regression, this was always broken, it just takes a lot of I/O in the VM to materialize the regression | 19:54:50 |
| raitobezarius | You can try to revert the "real fix", apply the workaround and verify if this fixes your issues | 19:55:07 |
| raitobezarius | If it does, this is the folio management of 9pfs which is still broken atm | 19:55:15 |
 Christian Theune | ugh | 19:56:04 |
| Christian Theune | so yes | 19:56:07 |
| Christian Theune | in your mail, the last point: "massive io in the guest" is what is triggering in our cases, too | 19:56:22 |
| Christian Theune | and you mentioning folios makes me weep | 19:56:33 |
| Christian Theune | i already had a 3 year journey wrapped up of getting an xfs folio issue fixed last year -_- | 19:56:51 |
| raitobezarius | Well, you will be happy to know that the folio code is going to happen even more in more FS subsystems | 19:57:12 |
 Alyssa Ross | Didn't we switch to virtio-fs for VM tests? | 19:57:24 |
| Christian Theune | linus was not amused when he saw what was going on ... | 19:57:31 |
| Christian Theune | Alyssa Ross: 24.11 and 25.05 don't seem to be, might it have been more recent? | 19:58:15 |
| Christian Theune | raitobezarius: do you happen to have a patch set for 6.12.34 around that I can try out? | 19:58:51 |
| Alyssa Ross | Not more recent than 25.05 | 19:59:13 |
| Alyssa Ross | Ah it was buildInLinuxVM, not NixOS tests | 19:59:38 |
| Christian Theune | hmm. now ... how can i respond to that regression list thread so I get involved there ... o_O | 20:01:56 |
| Alyssa Ross | Download the raw message, open in it your mail client | 20:03:10 |
| Alyssa Ross | Although you might need lore to come back for that | 20:03:32 |
| Christian Theune | yeah, that's what i was trying to figure out | 20:03:46 |
| Christian Theune | but the other one at least has message ids | 20:03:56 |
| Christian Theune | i can google for those | 20:03:59 |
| Christian Theune | maybe i can find the raw message elsewhere | 20:04:05 |
| Alyssa Ross | raitobezariuscould presumably also forward it to you as an attachment | 20:04:32 |
| Christian Theune | yeah, that might be easiest. | 20:05:59 |
| Christian Theune | raitobezarius: i'll dm you | 20:06:05 |
| Christian Theune | ah, and apparently i can just apply the two mentioned commits. i'll try that out for my setup | 20:08:13 |
| Christian Theune | ah, there's only one commit id, so hunting the other patch ... | 20:10:57 |
| Christian Theune | alright, took this one (https://lkml.org/lkml/2024/10/21/1621) and building our tests with it now | 20:14:04 |
