Public bug reported: We hit an issue when a nfs server is unreachable and clients keep reconnecting to it causes syslog and kern.log files to be flooded with errors like:
kernel: xs_tcp_setup_socket: connect returned unhandled error -1 Approx 30.000 errors / second. This causes disk space to grow rapidly and fill the disk in a matter of minutes. Only solution appears to be to reboot the nfs servers. Nfs server is running longhorn 1.5.3 and client mounts options look like: ... type nfs4 (rw,relatime,vers=4.1,rsize=1048576,wsize=1048576,namlen=255,softerr,softreval,noresvport,proto=tcp,timeo=600,retrans=5,sec=sys,clientaddr=10.125.92.24,local_lock=none,addr=10.43.81.150) We did not experience this issue before longhorn introduced "soft" nfs options. We have a SUSE/Longhorn support ticket (01053865) for this and they suggested us to report this here.
