I've had some luck adding this line to my crontab: */1 * * * * ls /mnt/record
It seems by listing the contents of the mount every 60 seconds I stave off its death, but YMMV. It's definitely a hack, and I look forward to an actual fix, but in the meantime. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1687273 Title: Shared folder randomly not mounted Status in cifs-utils package in Ubuntu: Confirmed Status in linux package in Ubuntu: Confirmed Bug description: Hello Everybody, since last update from ubuntu 16.04.2, last night, my servers are randomly not able to read and write from shared folders. I got this message: lsof: WARNING: can't stat() cifs file system /mnt/record Output information may be incomplete. lsof: WARNING: can't stat() cifs file system /mnt/record Output information may be incomplete. lsof: WARNING: can't stat() cifs file system /mnt/record Output information may be incomplete. ... rsync: ERROR: cannot stat destination "/mnt/record/": Host is down (112) rsync error: errors selecting input/output files, dirs (code 3) at main.c(652) [Receiver=3.1.1] This comes from my cron script. When I type df -h it takes sometimes very long to get the list. And it also can be that the mounted share is disconnected and I have to mount -a (what also takes long) again. My fstab have this command: //address /mnt/storage cifs auto,nofail,iocharset=utf8,rw,credentials=/path/.smb,uid=1000,gid=1000,file_mode=0660,dir_mode=0770 0 0 My update list from last night was this: linux-image-4.4.0-75-generic:amd64 (4.4.0-75.96, automatic) linux-image-extra-4.4.0-75-generic:amd64 (4.4.0-75.96, automatic) linux-headers-4.4.0-75-generic:amd64 (4.4.0-75.96, automatic) linux-headers-4.4.0-75:amd64 (4.4.0-75.96, automatic) Upgrade: libdns-export162:amd64 (1:9.10.3.dfsg.P4-8ubuntu1.5, 1:9.10.3.dfsg.P4-8ubuntu1.6) linux-headers-generic:amd64 (4.4.0.72.78, 4.4.0.75.81) linux-libc-dev:amd64 (4.4.0-72.93, 4.4.0-75.96) mysql-client-5.7:amd64 (5.7.17-0ubuntu0.16.04.2, 5.7.18-0ubuntu0.16.04.1) libapt-inst2.0:amd64 (1.2.19, 1.2.20) mysql-server-5.7:amd64 (5.7.17-0ubuntu0.16.04.2, 5.7.18-0ubuntu0.16.04.1) libsystemd0:amd64 (229-4ubuntu16, 229-4ubuntu17) linux-image-generic:amd64 (4.4.0.72.78, 4.4.0.75.81) apt:amd64 (1.2.19, 1.2.20) mysql-server:amd64 (5.7.17-0ubuntu0.16.04.2, 5.7.18-0ubuntu0.16.04.1) udev:amd64 (229-4ubuntu16, 229-4ubuntu17) libapt-pkg5.0:amd64 (1.2.19, 1.2.20) libudev1:amd64 (229-4ubuntu16, 229-4ubuntu17) cifs-utils:amd64 (2:6.4-1ubuntu1, 2:6.4-1ubuntu1.1) dpkg:amd64 (1.18.4ubuntu1.1, 1.18.4ubuntu1.2) mysql-client-core-5.7:amd64 (5.7.17-0ubuntu0.16.04.2, 5.7.18-0ubuntu0.16.04.1) libisc-export160:amd64 (1:9.10.3.dfsg.P4-8ubuntu1.5, 1:9.10.3.dfsg.P4-8ubuntu1.6) linux-virtual:amd64 (4.4.0.72.78, 4.4.0.75.81) systemd-sysv:amd64 (229-4ubuntu16, 229-4ubuntu17) distro-info-data:amd64 (0.28ubuntu0.2, 0.28ubuntu0.3) systemd:amd64 (229-4ubuntu16, 229-4ubuntu17) mysql-common:amd64 (5.7.17-0ubuntu0.16.04.2, 5.7.18-0ubuntu0.16.04.1) apt-utils:amd64 (1.2.19, 1.2.20) libmysqlclient20:amd64 (5.7.17-0ubuntu0.16.04.2, 5.7.18-0ubuntu0.16.04.1) linux-headers-virtual:amd64 (4.4.0.72.78, 4.4.0.75.81) linux-image-extra-virtual:amd64 (4.4.0.72.78, 4.4.0.75.81) thermald:amd64 (1.5-2ubuntu3, 1.5-2ubuntu4) qemu-guest-agent:amd64 (1:2.5+dfsg-5ubuntu10.10, 1:2.5+dfsg-5ubuntu10.11) libfreetype6:amd64 (2.6.1-0.1ubuntu2.1, 2.6.1-0.1ubuntu2.2) linux-image-virtual:amd64 (4.4.0.72.78, 4.4.0.75.81) libdpkg-perl:amd64 (1.18.4ubuntu1.1, 1.18.4ubuntu1.2) mysql-server-core-5.7:amd64 (5.7.17-0ubuntu0.16.04.2, 5.7.18-0ubuntu0.16.04.1) libxslt1.1:amd64 (1.1.28-2.1, 1.1.28-2.1ubuntu0.1) dpkg-dev:amd64 (1.18.4ubuntu1.1, 1.18.4ubuntu1.2) I saw that somebody else has the same problem: https://askubuntu.com/questions/910058/updates-broke-cifs-smb-mounts- in-16-04 I had to remove the latest kernel update, after that it works.
