--- Begin Message ---Package: nfs-common Version: 1:1.2.8-9 Severity: important I have a typical environment with a nfs server and some clients with home there, or shared resources. In the server I have a Wheezy (in one server with 3.12-0.bpo.1-amd64 version and in other 3.2.63). My clients basically are Wheezy but I'm preparing to Jessie and I wanted to test the upgrade. I have realized that in the two cases that I have tested (at home and work) both, with the same parameters (fstab) that worked "normal" with Wheezy, now, they have an horrible performance in write operations. I'm having differences of several order of magnitude (37,9 KB/s Jessie vs 17,4 MB/s) For instance: Wheezy machine: $ dd if=/dev/zero of=myrandom bs=1024 count=1000 1000+0 registres llegits 1000+0 registres escrits 1024000 octets (1,0 MB) copiats, 0,0590127 s, 17,4 MB/s Jessie machine $ dd if=/dev/zero of=myrandom bs=1024 count=1000 1000+0 registres llegits 1000+0 registres escrits 1024000 octets (1,0 MB) copiats, 27,0021 s, 37,9 kB/s I hope that the kernel developers have changed some default parameter and I have it wrong. But, with this version of the kernel, my nfs clients cannot work well. I'm open to make any test or provide any needed information. -- Package-specific info: -- rpcinfo -- program vers proto port service 100000 4 tcp 111 portmapper 100000 3 tcp 111 portmapper 100000 2 tcp 111 portmapper 100000 4 udp 111 portmapper 100000 3 udp 111 portmapper 100000 2 udp 111 portmapper 100024 1 udp 57366 status 100024 1 tcp 33506 status -- /etc/default/nfs-common -- NEED_STATD= STATDOPTS= NEED_IDMAPD=yes NEED_GSSD= -- /etc/idmapd.conf -- [General] Verbosity = 5 Pipefs-Directory = /run/rpc_pipefs Domain = alaxarxa.net [Mapping] Nobody-User = nobody Nobody-Group = nogroup [Translation] Method = nsswitch -- /etc/fstab -- #nfs4 cami:/recursos /home/recursos nfs4 auto,rw,nodev,sync,_netdev,retry=10,rsize=65536,wsize=65536,soft,noatime,intr 0 0 -- /proc/mounts -- cami:/recursos /home/recursos nfs4 rw,sync,nodev,noatime,vers=4.0,rsize=65536,wsize=65536,namlen=255,soft,proto=tcp,port=0,timeo=600,retrans=2,sec=sys,clientaddr=192.168.1.8,local_lock=none,addr=192.168.1.254 0 0 -- System Information: Debian Release: 8.0 APT prefers testing APT policy: (500, 'testing'), (1, 'unstable') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 3.16.0-4-amd64 (SMP w/4 CPU cores) Locale: LANG=ca_ES.UTF-8, LC_CTYPE=ca_ES.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages nfs-common depends on: ii adduser 3.113+nmu3 ii initscripts 2.88dsf-58 ii libc6 2.19-13 ii libcap2 1:2.24-6 ii libcomerr2 1.42.12-1 ii libdevmapper1.02.1 2:1.02.90-2 ii libevent-2.0-5 2.0.21-stable-1.1 ii libgssapi-krb5-2 1.12.1+dfsg-16 ii libk5crypto3 1.12.1+dfsg-16 ii libkeyutils1 1.5.9-5+b1 ii libkrb5-3 1.12.1+dfsg-16 ii libmount1 2.25.2-4 ii libnfsidmap2 0.25-5 ii libtirpc1 0.2.5-1 ii libwrap0 7.6.q-25 ii lsb-base 4.1+Debian13+nmu1 ii rpcbind 0.2.1-6 ii ucf 3.0030 Versions of packages nfs-common recommends: ii python 2.7.8-2 Versions of packages nfs-common suggests: pn open-iscsi <none> pn watchdog <none> -- Configuration Files: /etc/default/nfs-common changed: NEED_STATD= STATDOPTS= NEED_IDMAPD=yes NEED_GSSD= -- no debconf information
