I am somewhat new to Solaris - and very new when it comes to mounts.
My problem is that when I installed Solaris, I allocated way too little diskspace to my / mount (it first became obvious now, however, because of new needs).
As you can see, I have lots of space allocated to /export/home.
My question is - can I (and how?) do I take 100 gb of space from /export/home and allocate to my / mount without literally screwing my system over?
The primary reason for this is that installing Oracle on my server requires at least 1,1-1,5 gb of available disk space on /. As you can see above, I only have 741 mb free disk space.
I hope you can point me in the right direction.
Please keep in mind that I never have played with mounts before on UNIX, so please be gentle
Hi there,
When I run top on my machine it says I have 497M swap space in use, and 380M swap space free,
but I have only allocated 512M swap space to the machine!!!!
Does anyone know how swap used is calculated in the top command?
Thanks... (1 Reply)
Now, i know a ufs file system can be increased using mkfs but hwo do I take space from a file system and add it to another file system? at my job here, that seems to be possible because I see request on it almost every day.
what is the exact command to do this and does the system need to be... (1 Reply)

Hi,
On one of our solaris servers, the root partition has filled up,(it was poorly sized in the first place), Does anyone have any advice about the best way to add space to a partition. I'm sure I've read how to do this somewhere before but just can't remember...:(

I searched the archives first, but found that there are alot of mixed answers on whether swap space can or can not be increased. Some postings said swap space can be increased using the swap or growfs commands while other postings said you can not increase the permanent size of the swap space.

Hi
I have a mount point that is in production environment, and is currently filled up.
more space has been presented from same original source (EVA).
Problem;
1. Can't see presented space
2. After I discover the presented space, how do I go about adding this new space to existing mount point.... (9 Replies)
Hi ,
I Would like to know the space allocated by adding up all the allocated space to group of filesystems ..
example ,

vfstab(4) File Formats vfstab(4)NAME
vfstab - table of file system defaults
DESCRIPTION
The file /etc/vfstab describes defaults for each file system. The information is stored in a table with the following column headings:
device device mount FS fsck mount mount
to mount to fsck point type pass at boot options
The fields in the table are space-separated and show the resource name (device to mount), the raw device to fsck (device to fsck), the
default mount directory (mount point), the name of the file system type (FS type), the number used by fsck to decide whether to check the
file system automatically (fsck pass), whether the file system should be mounted automatically by mountall (mount at boot), and the file
system mount options (mount options). (See respective mount file system man page below in SEE ALSO for mount options.) A '-' is used to
indicate no entry in a field. This may be used when a field does not apply to the resource being mounted.
The getvfsent(3C) family of routines is used to read and write to /etc/vfstab.
/etc/vfstab can be used to specify swap areas. An entry so specified, (which can be a file or a device), will automatically be added as a
swap area by the /sbin/swapadd script when the system boots. To specify a swap area, the device-to-mount field contains the name of the
swap file or device, the FS-type is "swap", mount-at-boot is "no" and all other fields have no entry.
EXAMPLES
The following are vfstab entries for various file system types supported in the Solaris operating environment.
Example 1: NFS and UFS Mounts
The following entry invokes NFS to automatically mount the directory /usr/local of the server example1 on the client's /usr/local directory
with read-only permission:
example1:/usr/local - /usr/local nfs - yes ro
The following example assumes a small departmental mail setup, in which clients mount /var/mail from a server mailsvr. The following entry
would be listed in each client's vfstab:
mailsvr:/var/mail - /var/mail nfs - yes intr,bg
The following is an example for a UFS file system in which logging is enabled:
/dev/dsk/c2t10d0s0 /dev/rdsk/c2t10d0s0 /export/local ufs 3 yes logging
See mount_nfs(1M) for a description of NFS mount options and mount_ufs(1M) for a description of UFS options.
Example 2: pcfs Mounts
The following example mounts a pcfs file system on a fixed hard disk on an x86 machine:
/dev/dsk/c1t2d0p0:c - /win98 pcfs - yes -
The example below mounts a Jaz drive on a SPARC machine. Normally, the volume management daemon (see vold(1M)) handles mounting of remov-
able media, obviating a vfstab entry. If you choose to specify a device that supports removable media in vfstab, be sure to set the mount-
at-boot field to no, as below. Such an entry presumes you are not running vold.
/dev/dsk/c1t2d0s2:c - /jaz pcfs - no -
For removable media on a SPARC machine, the convention for the slice portion of the disk identifier is to specify s2, which stands for the
entire medium.
For pcfs file systems on x86 machines, note that the disk identifier uses a p (p0) and a logical drive (c, in the /win98 example above) for
a pcfs logical drive. See mount_pcfs(1M) for syntax for pcfs logical drives and for pcfs-specific mount options.
Example 3: CacheFS Mount
Below is an example for a CacheFS file system. Because of the length of this entry and the fact that vfstab entries cannot be continued to
a second line, the vfstab fields are presented here in a vertical format. In re-creating such an entry in your own vfstab, you would enter
values as you would for any vfstab entry, on a single line.
device to mount: svr1:/export/abc
device to fsck: /usr/abc
mount point: /opt/cache
FS type: cachefs
fsck pass: 7
mount at boot: yes
mount options:
local-access,bg,nosuid,demandconst,backfstype=nfs,cachedir=/opt/cache
See mount_cachefs(1M) for CacheFS-specific mount options.
Example 4: Loopback File System Mount
The following is an example of mounting a loopback (lofs) file system:
/export/test - /opt/test lofs - yes -
See lofs(7FS) for an overview of the loopback file system.
