I have a machine: SunOS <server> 5.9 Generic_117171-15 sun4u sparc SUNW,Sun-Fire-480R
It has these filesystems:
The machine has two systems disks which are software mirrored:
The problem is: why is the swap showing to be 27Gb in size when the partition is only 16Gb? I performed a swap -l and see no other swapfiles:
Is this because I have my swap partition mirrored?
Should I break the swap mirror, or is this just fine..?
Hy all,
i've a little problem with the size of the swap. I've an old solaris machine, with 4Go, and swap is taking 500Mo for only 1% used at any time.
So : how can i change this size without problems ?????

Hello all,
I just got a laptop with redhat linux 7.2 installed, but during the installation the installer only put 1gig of sawp space( this laptop has 1gig of RAM). To my understanding when creating swap space, the size is determine by double the RAM. Therefore my question is that how do I... (2 Replies)
few questions
a. where can I find the RAM of a server? im about to install redhat on a server (reformat). need to know because it will be my basis for swap size. i saw something line 3048MB detected upon boot. is this the memory?
b. what is the command in lunux to check the original size of... (2 Replies)
Dear All,
How to increase the swap size when physicall memory reaches 60 %. OR it can be only done after the physicall memory is full.

Hi All,
I want to know how to understand the actual swap size.
My o/p shows as below
root@ecovs1a # swap -s
total: 4546056k bytes allocated + 358856k reserved = 4904912k used, 5046688k available

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.
