Hi,
I set up a RAID 5 configuration and for some reason the volumes won't mount when the system boots. I have to manually mount them from the command line and all is fine.
Here's the vfstab entries:

Hello All,

Few weeks ago I had posted a message in this forum about the problem I had when I replaced my two scsi disks and tried rebuild raid1 array.
I somehow managed to up the system with working raid1 array.
But the main problem persisted..
i.e when I reboot the system, mounting... (0 Replies)
Hi.
I'm trying to copy multiple folders from the remote machine to the local machine. I wrote a batch file to run an ftp window.
The problem I am having is that the only command to copy files is mget *, and this copies only files, not folders.
For example, ftp ts555
cd ts555/test

mqueuefs
MQUEUEFS(5) BSD File Formats Manual MQUEUEFS(5)NAME
mqueuefs -- POSIX message queue file system
SYNOPSIS
To link into kernel:
options P1003_1B_MQUEUE
To load as a kernel loadable module:
kldload mqueuefs
DESCRIPTION
The mqueuefs module will permit the FreeBSD kernel to support POSIX message queue. The module contains system calls to manipulate POSIX mes-
sage queues. It also contains a file system to implement a view for all message queues of the system. This helps users to keep track of
their message queues and make it more easily usable without having to invent additional tools.
The most common usage is as follows:
mount -t mqueuefs null /mnt/mqueue
where /mnt/mqueue is a mount point.
It is possible to define an entry in /etc/fstab that looks similar to:
null /mnt/mqueue mqueuefs rw 0 0
This will mount mqueuefs at the /mnt/mqueue mount point during system boot. Using /mnt/mqueue as a permanent mount point is not advised as
its intention has always been to be a temporary mount point. See hier(7) for more information on FreeBSD directory layout.
Some common tools can be used on the file system, e.g.: cat(1), chmod(1), chown(8), ls(1), rm(1), etc. To use only the message queue system
calls, it is not necessary for user to mount the file system, just load the module or compile it into the kernel. Manually creating a file,
for example, ``touch /mnt/mqueue/myqueue'', will create a message queue named myqueue in the kernel, default message queue attributes will be
applied to the queue. It is not advised to use this method to create a queue; it is better to use the mq_open(2) system call to create a
queue as it allows the user to specify different attributes.
To see the queue's attributes, just read the file:
cat /mnt/mqueue/myqueue
