Have you tried setting fsid and not using the mounting of root path like that? Because besides that I simply can't reproduce this on 5.15 on Ubuntu. It works fine...

Not sure but at most it is a FUSE NFS issue as mergerfs is not behaving any differently between these two situations. I'll do some more investigation and talk to...

When was the strace of mergerfs taken? While in that broken state? If so... mergerfs looks fine. Preferably you would trace just before issuing a request to mergerfs mount and...

NFS does not like out of band changes. Particularly NFSv4. If you have a NFS export and then on the host you export from modify the filesystem straight... you can...

Hmm.. Well the "stat" clearly worked though you didn't stat the file you statfs'ed it. But the statfs clearly worked and you can see the request in mergerfs. The `ls`...

See the caching section of the docs. Turn off entry and attr too. And yes, could help to trace that setup.

If I knew I'd ask for it. The kernel isn't forwarding the request. `44419 15:35:19.951799 statx(AT_FDCWD, "/Storage", AT_STATX_SYNC_AS_STAT|AT_SYMLINK_NOFOLLOW|AT_NO_AUTOMOUNT, STATX_MODE|STATX_NLINK|STATX_UID|STATX_GID|STATX_MTIME|STATX_SIZE, 0x7ffcf234e990) = -1 EIO (Input/output error) ` vs ``` 33344 15:35:19.359147...

@Janbong And are you using NFS too? @gogo199432 Are your mergerfs and NFS settings the same as the original post? Have you tried modifying NFS settings? Do you have other...

Yes, but was it the same kernel? Same NFS config? Same NFS version?
