Hello Misc, I have run into an odd problem. Machine A is running a model that writes files periodically to a file system NFS mounted from machine B. Machine B backs up this file system periodically to machine C via rsync. If this backup runs while machine A is writing a file, the model on A crashes. The model is written in Go.
I recently updated the disk containing this file system on machine B to an 8 TB disk from a 2 TB disk. The problem didn't occur with the 2 TB disk. I believe that this disk used FFS-1 while the new disk uses FFS-2. Any ideas on this? I haven't tried digging into the Go write code yet. Here is the fstab entry on machine B: 6a99351289f050d4.a /data.gy ffs rw,nodev,nosuid 1 2 Here is the rsync command updating from B to C: /usr/local/bin/rsync -avxl --delete /data.gy/ gryphon:/data.gy Here is the fstab entry on machine A: loro:/data.gy /data.gy nfs rw,nodev,nosuid,noatime 0 0 Here is the entry in the exports file on machine B (the problem occurs for A equal to all of gy01 to gy08): /data.gy me merlin gy01 gy02 gy03 gy04 gy05 gy06 gy07 gy08 Are there any other diagnostics that would be useful?
