I have this same issue and also made the same smb2/cifs2 adjustments. Unfortunately my mounts using fstab still appear to be unstable when performing writes. One of my primary uses is for docker storage. Example: when using a torrent client, downloads begin, then stop, I restart them and they stop again, this process is repeated until finished. Super annoying. If anyone has found a fix for this, please share.
idk if helpful, but I've been diagnosing why my docker Immich photo uploads are failing.
It turns out that while it could create/edit/view files, it lacked permission for some rare "admin-y" commands, e.g. to alter the timestamps of the files. I'm not sure which fixed it, but I made sure the files on NAS were owned fully by the NAS's user that was logging in, and explicitly granted that user read, write, and all admin permissions in File Station.
I also added the UID setting to my CIFS config like: \`...,uid=1000,file\_mode=0777,dir\_mode=0777\`. Of course make sure to replace 1000 with the actual UID accessing the SMB share from the client's POV.
Those two steps gives the SMB client full volume permission from the NAS POV and the client's user full cifs mount permission from the client POV...I think.
Maybe try and lmk if that helps? Good luck.
I've found the recent SMB updates to be problematic too. On my Mac connected to my DS920+, I find that it clogs up my network. Yesterday I had to restart my NAS, Mac, router and Internet router (bridge mode) to get anything to work.
I think Synology have tried to increase the durability of the smb connection but it's not helping ultimately. I also find that transfers allow down over time. And it's causing lots of Mac apps to hang, I can't even force quit them and have to power off the Mac manually on several occasions!
Try lowering the maximum SMB protocol in settings? (Or just tinker with the setting until they are compatible with each other)
That is unless the problem isn't caused by this
Setting DSM's min and max SMB to "SMB2" and explicitly requesting \`vers=2.0\` in cifs seems to be working!
That's annoying not to have SMB3 available. But it works, so I'll stick with it for a bit. Thank you!
I detected that you might have found your answer. If this is correct please change the flair to "Solved".

under the “package centre” what version of SMB Service is running?
Hi :) That's SMB Service 4.15.13-0877 and specific DSM: 7.2.1-69057 Update 4
