Configuring NFS in SmartOS

In the past, I've written up configuring NFS in Solaris, FreeBSD,
and Linux. Now I'll turn my focus to SmartOS. Briefly, NFS
(network file system) provides access to remote filesystems which
appear similar to local resources on client hosts. The following

Repartitioning Contiguous Space in Linux

As a follow up to the same under Solaris, I thought I'd detail
repartitioning in-use, contiguous space in Linux. To recap the
situational setup, a filesystem (FS) has run out of space and the data
contained on it couldn't be removed or compressed to free up space.

Repartitioning Contiguous Space in Solaris

Recently, a system owner aked me for help because they had run out of space on one of their filesystems (FS). As a result, this was causing problems with the application they had running. Unfortunately, this FS was being used for database files so we couldn't just remove or

Enabling Local FS Quotas in Linux

Quotas allow you to limit the amount of space a user or group can use
and / or the number of files a user or group can create on a filesystem
(FS).  The following shows how to set up these quotas and the expected
user experience.  Our host details for this are:

Having written up Solaris and Linux, it's time to take a look at

Configuring NFS in Linux

As a follow up to 'Configuring NFS in Solaris', we turn to the same
in Linux.  Briefly, NFS (network file system) provides access to remote
filesystems which appear similar to local resources on client hosts.
The following focuses on simple NFS server and client configuration in

Configuring NFS in Solaris

Networked environments allow for the sharing of many resources, including
filesystems (FS).  As a long time industry standard in UNIX, NFS (network
file system) provides access to remote filesystems which appear similar
to local resources on client hosts.  Since Sun Microsystems originally

Breaking and Syncing an MD Root Mirror

Here's one of those times where I thought, "I wonder", as in I wonder if
I can break an MD root mirror and sanely recreate it.  You can do so with
other software RAID solutions so why not here?  Well, you can.  There is
nothing short about this procedure, taking 80+ commands to accomplish.

Creating an MD Root Mirror in Linux

For whatever reason, you originally set up your Linux host without a root
disk mirror and now you want it mirrored.  One could say "just re-install,"
but surely there is another way, and there is.  The solution isn't quick
or simple, though it isn't impossible.  Our host details are:

Disk Cloning in Linux

A while back, I wrote up how to clone a disk in Solaris and in FreeBSD,
yet somehow managed to overlook writing up how to do so in Linux.
This write up is to rectify just that, how to clone a disk, in this case,
the root disk, in Linux.  The following are our setup details:

Adding Swap Space in Linux

We've discussed FreeBSD and Solaris, now it's time to have a look at
adding swap space in Linux.  As previously handled, the setting up
of swap on a free disk partition or else a swap file is discussed.
The following details our example host:

Adding Swap Space in Solaris

Following up on "Adding Swap Space in FreeBSD", we take a look at the same
with Solaris.  As in the FreeBSD writeup, the usage of a free disk slice
or else a swap file is discussed.  The following details our host info:

Adding Swap Space in FreeBSD

While it shouldn't occur too frequently, it is likely at some point as a
sysadmin, you will need to add additional swap space to a box.  At that
time, your options will be to use a free disk partition with suitable
space or to create a swapfile on an existing filesystem.  The following

FreeBSD Issue with Solaris NFS Shares

In a past NAS migration attempt, it was discovered that FreeBSD boxes
don't necessarily play well with NFS mounts shared from Solaris boxes
when the mount IP is on a virtual interface.  The reason behind this
issue is that Solaris, in dealing with virtual interfaces, responds

Replacing VxVM with SVM for the rootdisk

The purpose of this post is to illustrate how to replace Veritas Volume
Manager (VxVM) with Sun Volume Manager (SVM) for control of the root disk
while leaving application volumes under VxVM control.  I had originally
tested this against Solaris 9 sparc running VxVM 4.0, though have updated
