Hi, I'm playing with pNFS (spnfs layouts) using one MDS and one DS. I have a client that mount pNFS volume. I can touch (create) files on that volume immediately: time touch c real 0m0.005s user 0m0.000s sys 0m0.000s But creating files with a content suffers from approx. 15 secs timeout: dd if=/dev/zero of=testf10 bs=1M count=1 1+0 records in 1+0 records out 1048576 bytes (1.0 MB) copied, 15.1156 s, 69.4 kB/s overwriting the same file works OK: dd if=/dev/zero of=testf10 bs=1M count=1 1+0 records in 1+0 records out 1048576 bytes (1.0 MB) copied, 0.0258294 s, 40.6 MB/s I think this is an interesting part of the debug logs: [69615.791232] pnfs_writeback_done: Begin (status -10008) [69615.791238] put_lseg: lseg ffff88003b987840 ref 7 valid 1 [69615.794450] NFS: 6195 nfs_writeback_done (status -10008 count 8192) [69615.794450] pnfs4_write_done DS write [69615.794450] nfs41_sequence_done: Error 0 free the slot [69615.794450] nfs4_free_slot: free_slotid 0 highest_used_slotid 5 [69615.794450] <-- pnfs4_write_done status= -11 [69615.990137] filelayout_write_call_done new off 8192 orig offset 8192 Any ideas? -- Lukáš Hejtmánek -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
