""We recently ran across a strange higgs-bugson that manifested itself in a critical system […] A higgs-bugson is a bug that is reported in practice but difficult to reproduce, […]

The Linux kernel does not actually implement this cache as suggested by the RFC, so I wrote a kernel patch to add this functionality and mailed it off upstream. I also learned that the FreeBSD kernel actually already implements this, so this is new-to-Linux but not new-to-NFS.

[…]

Both of these patches are now upstream and will be available in Linux 6.16.""

NFS: the "Not For Sure" filesystem.

Try writing several hundred thousand files, and one or two won't, or worse, will do so truncated. Doesn't matter if from python or from java, calling sync on the file handle or not. Some will fail. Writing software as crashware that can rerun operations when needed is a good way to cope with this.

In retrospect, it's amazing it works at all, considering – multiple computers, each with many CPU cores, all hitting the same file system at once.

#NFS just killed a #Synology DS213j #NAS running DSM4.2.

Everything was fine and I tried to mount a NFS share and the device went mad. Power button flashes blue, and it doesn't respond to the network, it's still drawing power but it's essentially a brick.

I managed to recover it from this before but I'm not 100% sure what I actually did to fix it, but I'm going to disable NFS on it to make sure no one tries that again.

Thanks for the help, everyone! #NFS is the way to go, and a lot simpler than I thought. For anyone discovering this later, the guide I'm using is this one: github.com/zilexa/Homeserver/tree/master/Filesystems-guide/networkshares_HowTo-NFSv4.2 Credits to everyone for the suggestions, ideas, and assurance that this isn't going to be as hard as I thought it would be: @yo, @dlakelan, @tripplehelix, @quanin, @modulux,

Ich stehe hier vor einem riesigen Haufen Problemen rund um #Docker, #Swarm, #NFS und #Netzwerk.
Die Feiertage stehen vor der Tür und ich habe Bereitschaft im Betriebsurlaub.

Das wird Spannend...

Ansonsten stehen da noch weitere ~50 Tickets mit Prio 1 an.

Yaaay.

#Synology, #Nextcloud and #NixOS question:
I have 1 Synology host, where is want to store the data for my nextcloud users. It is exposed as #NFS share. My NixOS host, where nextcloud runs should now access those shares.

Problem: I seem to get get the permissions wrong on the shared folder. Even though i have the same UID/GID for the `nextcloud` user on both systems, Nextcloud fails to start with permission error (cannot create directories).
Is the `www-data` user also involved?
