February 22, 20215 yr I searched for the answer for a couple of hours without success... So I figured I would ask here! Recently, I had to do a fresh install of Pop!OS on my main rig because I managed to destroy it! Since then, when trying to transfer large file to my Unraid server through NFS, I always get I/O errors and file corruption. I have a feeling it has to do with caching but I am not certain... can someone point me in the right direction? here is an example of how my shares are mounted in fstab: [unraid server ip]:/mnt/user/[mount point] /home/normand/NFS/NORMAND-NAS-01/[mount point] nfs defaults,timeo=14,soft 0 0 I remember having similar issues in the past but can't remember what I did to fix it. Have a nice day all! Edited February 24, 20215 yr by Normand_Nadon
March 13, 20215 yr Author Sorry for bumping my own thread again... but this has become a nightmare! I can't send medium to large files to my server because they always give me I/O errors. I am mostly certain it has something to do with caching, but I can't figure-out how to solve it...
March 13, 20215 yr Do you try other NFS mounting method ? I always transfer file through NFS without problem. Edited March 13, 20215 yr by Vr2Io

And using it in Unraid for some time too. I had a new error I have never seen before just now... Maybe it will give off a clue... It said "Splicing error" and again, the I/O thing I remember trying to mount my NFS shares with an older version of NFS before, but can't remember if it helped... When I transfer files, I see that the client's buffer fills super fast before the transfer starts (like 2Gb in a few seconds)... that is why I suspect cache or buffer issue.
March 13, 20215 yr Author There might be some issues here... The block size seems huge... doesn't it? I will try mounting with V2 instead of V3 and report EDIT: V2 does not even work, server refuses... Edited March 13, 20215 yr by Normand_Nadon
March 13, 20215 yr I haven't verify what version NFS protocol I use, because I haven't problem. But I believe I use v2. Pls have a try and update the result.

March 13, 20215 yr What OS in other end ? Can be change/config the protocol ver. in other end ? Edited March 13, 20215 yr by Vr2Io
March 13, 20215 yr Author I am running Pop!OS 20.10 (Ubuntu derivative) When I force nfs V2 in /etc/fstab, I get the "protocol not supported" error
March 13, 20215 yr Author Ok... I changed my mounting method from soft to: hard,intr I know this will get me other kinds of issues if the server goes down, but at least, I am able to upload files now!
