[JIRA] [core] (JENKINS-10442) RestartNotSupportedException when trying to do safeRestart

[stevejansen_git...@icloud.com (JIRA)]

Steve Jansen commented on JENKINS-10442 RestartNotSupportedException when trying to do safeRestart I believe I figured this out. After experiencing this problem on a CentOS 6.5 VM, I decided to start the Jenkins server interactively (eg., java -jar jenkins.war ... ) I saw a very curious warning: Nov 21, 2014 10:46:51 PM jenkins.diagnosis.HsErrPidList <init> WARNING: Failed to list up hs_err_pid files java.lang.UnsatisfiedLinkError: /tmp/jna/jna4408307760862063272.tmp: /tmp/jna/jna4408307760862063272.tmp: failed to map segment from shared object: Operation not permitted This reminded me of a very similar problem on CentOS 6.5 with ruby-build that I documented @ https://github.com/sstephenson/ruby-build/issues/604#issuecomment-54310466 The cause seems to be when $TMPDIR is mounted as noexec. Just re-mount your temp dir and tmpfs as executable: $ mount /dev/mapper/vglocal20140828-root00 on / type ext4 (rw) proc on /proc type proc (rw) sysfs on /sys type sysfs (rw) devpts on /dev/pts type devpts (rw,gid=5,mode=620) tmpfs on /dev/shm type tmpfs (rw,noexec,nosuid,nodev) /dev/sda1 on /boot type ext3 (rw) /dev/mapper/vglocal20140828-tmp00 on /tmp type ext4 (rw,noexec,nosuid,nodev) /dev/mapper/vglocal20140828-log00 on /var/log type ext4 (rw) none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw) I was able to resolve by removing the noexec option from /tmp and tmpfs and re-mounting both: $ cp /etc/fstab /tmp/~fstab $ sudo vi /etc/fstab $ diff /tmp/~fstab /etc/fstab 11c11 < /dev/mapper/vglocal20140828-tmp00 /tmp ext4 defaults,nosuid,nodev,noexec 1 2 --- > /dev/mapper/vglocal20140828-tmp00 /tmp ext4 defaults,nosuid,nodev 1 2 14c14 < tmpfs /dev/shm tmpfs defaults,nosuid,nodev,noexec 0 0 --- > tmpfs /dev/shm tmpfs defaults,nosuid,nodev 0 0 $ sudo mount -o remount /tmp $ sudo mount -o remount tmpfs $ mount /dev/mapper/vglocal20140828-root00 on / type ext4 (rw) proc on /proc type proc (rw) sysfs on /sys type sysfs (rw) devpts on /dev/pts type devpts (rw,gid=5,mode=620) tmpfs on /dev/shm type tmpfs (rw,nosuid,nodev) /dev/sda1 on /boot type ext3 (rw) /dev/mapper/vglocal20140828-tmp00 on /tmp type ext4 (rw,nosuid,nodev) /dev/mapper/vglocal20140828-log00 on /var/log type ext4 (rw) none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
