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

geom_uncompress
GEOM_UNCOMPRESS(4) BSD Kernel Interfaces Manual GEOM_UNCOMPRESS(4)NAME
geom_uncompress -- GEOM based compressed disk images
SYNOPSIS
To compile this driver into the kernel, place the following line in your kernel configuration file:
options GEOM_UNCOMPRESS
Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):
geom_uncompress_load="YES"
DESCRIPTION
The geom_uncompress framework provides support for compressed read only disk images. This allows significant storage savings at the expense
of a little CPU time on each read. Data written in the GEOM label area allows geom_uncompress to detect compressed images which have been
created with mkulzma(8) or mkuzip(8) and presented to the kernel as a logical disk device via md(4). geom_uncompress creates a unique
md#.uncompress device for each image.
The geom_uncompress device is subsequently used by the FreeBSD kernel to access the disk images. The geom_uncompress driver does not allow
write operations to the underlying disk image. To check which md(4) devices match a given geom_uncompress device:
# geom uncompress list
Geom name: md0.uncompress
Providers:
1. Name: md0.uncompress
Mediasize: 52428800 (50M)
Sectorsize: 512
Mode: r1w0e0
Consumers:
1. Name: md0
Mediasize: 20864000 (20M)
Sectorsize: 512
Mode: r1w0e0
