an NFSERR_STALE error reported via a LayoutReturn. The current FreeBSD client can generate these errors for an operational DS while doing a recovery of a mirror after a mirrored DS has been repaired. I am not sure why these errors occur, but my best current guess is a race between the Layout Recall issued by the kernel code run from pnfsdscopymr(8) and a Read operation on the DS for the file bing copied. The errors are not fatal, since the client falls back on doing I/O through the MDS, which can do the I/O successfully as a proxy. (The fact that the MDS can do this indicates that the file does still exist on the functioning DS.) This change only affects the pNFS server and only when a client does a LayoutReturn with the NFSERR_STALE error report. |
