Hi everyone,
I'm running a simple test with ganesha-next (but the issue exists at least
in latest V2.5.5-stable):
$ sudo mount -t nfs -o v4.0,users,nolock,soft,timeo=2,retrans=3 127.0.0.1:/
/mnt/nfs
$ dd if=/dev/zero of=/mnt/nfs/dump/pw.1 bs=1024k count=2048 conv=fdatasync
dd: error writing '/mnt/nfs/dump/pw.1': Input/output error
1616+0 records in
1615+0 records out
1693450240 bytes (1,7 GB, 1,6 GiB) copied, 8,28076 s, 205 MB/s
$ sudo mount -t nfs -o users,nolock,soft,timeo=2,retrans=3 127.0.0.1:/
/mnt/nfs
$ dd if=/dev/zero of=/mnt/nfs/dump/pw.1 bs=1024k count=2048 conv=fdatasync
2048+0 records in
2048+0 records out
2147483648 bytes (2,1 GB, 2,0 GiB) copied, 6,27708 s, 342 MB/s
The second mount is using nfs v4.1.
I don't have anything special in my configuration.
If I do the dd with a blocksize of 512k, it works fine.
If I set rsize/wsize to 524288 as mount options, the dd with bs=1024k still
fails.
The only log line I get is the following:
25/09/2018 13:47:25 : epoch 5baa2036 : caipirinha :
ganesha.nfsd-2381[svc_182] rpc :TIRPC :EVENT :svc_ioq_flushv() writev
failed (104)
Thanks for your help.
Best Regards
