【问题描述】：

我使用 Ubuntu 14.04 64 位安装 LogicBlox 3.10 当我尝试做lb-services start 它提示我 error: service 'BloxPager' did not start. Aborting.

后续~/lb_deployment/logs/current/BloxPagerDaemon.log中的内容

在/etc/fstab中，内容为

# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).

我应该如何改变它？

顺便说一句，在 /dev/shm 中，我尝试删除除 LB_ubuntu 之外的所有内容，但似乎没有用。

出现了一个快速的 Google 搜索： http://forums.fedoraforum.org/showthread.php?t=275653

该线程描述了当 /etc/fstab 中还没有条目时如何更改 /dev/shm 的默认大小。

【解决方案2】：

您是否尝试过 LB_PAGER_FORCE_START 设置？

将以下行添加到您的 .bashrc 将阻止警告

导出 LB_PAGER_FORCE_START=""
