UNIX for Dummies Questions & Answers

Greetings all,

I am Running SunOS 4.1.4 2 w/ Sparcstation 20. It's got 256 megs of ram, and it appears that there isn't a swap file setup.

When I execute vmstat 5 under the Memory column I am concerened about the following stat

avm
0

I used format to determine how the partitions are layed out and found one on sd0 partition b. I have read that SunOS normally puts the swap area here. But fstab did not have any entries for a swap area. So I added to fstab

/dev/sd0b / swap sw 0 0

the executed swapon -a

No messages but when viewing vmstat I still have avm = 0

Any ideas on how to determine if the swap area is active or defined?

Thanks,

Don

Hi Don,

Have you tried using the mkswap command to ensure that the swap partition has been created.

The following should be all that's required:

mkswap /dev/sd0b

Once that's been done it should be okay to run:

swapoff /dev/sd0b
swapon /dev/sd0b
