As I mentioned earlier, I captured the nfs conversation between my laptop (Leap 15.4, same client as before) and the QNAP NAS server (details in description). As a summary: * showmount works * mount blocks indefinitely, as before. I stopped after 10mn. Looking at the capture (mount_ls_umount_kernel_46.1.pcapng.gz versus mount_ls_umount_kernel_55.3.pcapng.gz): everything is similar until we reach request #82 on kernel .55.3. The call GETATTR with FSID,FS_Locations is sent and the server replies with NFS4ERR_DELAY. This specific GETATTR call is not present in the capture for kernel .46.1. Then the same sequence repeats indefinitely every 15s. Looking on the web, I found a very similar issue ~1 year ago: https://bugzilla.redhat.com/show_bug.cgi?id=2055362 The conclusion was: updating QNAP NFS Server could help... I'll do this and report. But in any case, even if the NFS Server doesn't behave correctly, the client shouldn't block indefinitely. This is a major issue to be solved on client side IMO. -- You are receiving this mail because: You are on the CC list for the bug.
