Try to mount a seocn SWAP space-- error" unable to find swap space signature"

Post by doctornul » Wed, 19 Mar 2003 03:17:09



I am trying to mount a second swap space by

1. created a additonal partiton of type 82 with  fdisk
2. added an addition line in the /etc/fstab  -- identical to my first swap
     /dev/hda8   swap  swap  defaults 0 0
3. reboot

When it rebooted, it complainted that it failed to mount the 2nd swap space.

I looked  at the hardware browser's drive info , my new swap drive's type
was assigned as "none" rather than the "linux-swap" as in my first swap...
despite that fdisk's report as  " linux swap"
I also looked at the dmesg, it was complaining about   " Unable to find
swap-space signature"

What did I miss ?

mkswap /dev/hda8
swapon /dev/hda8
As well as adding the line to /etc/fstab which corresponds to the
new swap partition.

1. plenty of swap space, but keep receiving error "swap space limit exceeded"

Syslog reports
  unix: WARNING: /tmp: File system full, swap space limit exceeded

But

  Filesystem            kbytes    used   avail capacity  Mounted on
  swap                 2423720   48480 2375240     3%    /tmp

The host:
  SunOS <hostname> 5.7 Generic_106541-16 sun4u sparc SUNW,Ultra-60

I ran vmstat 1 for some time and watched for available swap space to
go to zero. But the lowest it would go is 75kB.

When analyzing this problem, I ran into the following error twice, but
for different commands:
  Can't run command <command>
  fork(2) failed; no more memory

What's going on?

Thanks.
