Isn't cached swap somewhat an oxymoron? Why cache virtual? Am I misunderstanding this line from top?
Swap: 524120k total, 80760k used, 443360k free, 73448k cached

its not cached swap, they just put the cached on the end of the swap line because it fits.
I'll say this, its not often I see swap used > cached. that machine definately could use more memory.

Then it should read:
Swap: 524120k total, 80760k used, 443360k free; Cached: 73448k

I have 256MB total, yes. Want to donate to the fund? Guaranteed not tax deductible.

Hey all,
I am a newbie Linux admin so please give me a little slack.
I have a fully functional postfix mail server that started stalling at boot up after I mounted a remote samba share.
I have no clue where to start looking but removing the share is not an option for me.
Thanks,
Jason Ross

This makes no sense (yet).

What can you find in the log files? They´re inside /var/log/
Have more details, then search the internet (google, yahoo, etc). If you can´t find anything, tell us.

How are you mounting the share? What is the fstab line in question?

Thank you. Much better. the original was done by webmin so I don't know why it was wrong but it works now!!!

Here is the fstab line.
\10.0.0.11\users /backup smbfs defaults 0 0
Try having all your slashes as backslashes; //10.0.0.11/users /backup smbfs defaults 0 0
Jason Ross wrote:
\10.0.0.11\users /backup smbfs defaults 0 0
Change all your backslashes to two backslashes.
Why smbfs and not cifs?

There is a samba box that holds all the windows shares on it. It also runs a backup on the samba shares. The boss wanted the email server to be backed up to a folder on the samba share.

If they are both linux servers, why not nfs?

I'd like too, I am relatively new to this company (8 mos) and the only other tech has given up trying. Management's only contact with Linux is with samba. They are dead set on having everything samba. I have a medium amount of experience with Linux administration so I cannot come up with an explanation convincing enough for them.
PS: can I set the NFS to point to a sub folder in the samba share? Jason
The reason I asked Why smbfs and not cifs? is that the latter is newer.
Neither supports POSIX semantics, and I did have problems with Samba shares last time I accessed them regularly on Linux. On the basis of "once bitten, twice shy" I've not done so again for many years:-) Since Samba 1.x.
NFS sharing is 'the one true way' for Linux and Unix Here are some configured shares: [summer@bilby ~]$ ssh ns cat /etc/exports | grep /var/local/mirrors | grep -v Linux /var/local/mirrors/linux/tmp 192.168.0.0/16(rw,no_root_squash,async) /var/local/mirrors 192.168.0.0/16(ro,no_root_squash,async) [summer@bilby ~]$ Here is me accessing one: [summer@bilby ~]$ ls /net/ns//var/local/mirrors total 60 drwxr-xr-x 6 root 4096 Feb 4 07:19 Windows drwxr-xr-x 3 root 4096 Apr 12 2006 drdos drwxr-sr-x 22 root 4096 Dec 17 09:30 linux drwx------ 2 root 16384 Aug 3 2006 lost+found drwxrwxrwt 2 root 4096 Feb 25 00:35 tmp drwxr-xr-x 4 root 4096 Dec 31 2005 unix [summer@bilby ~]$ There's how I configured the client to automatically mount when required: [summer@bilby ~]$ grep net /etc/auto.master /net /etc/auto.net [summer@bilby ~]$ Here's another way to configure nfs mounts: [summer@bilby ~]$ grep nfs /etc/fstab kookaburra.demo.lan:/var/local /var/local nfs auto ns.demo.lan:/var/local/mirrors/linux/RHEL/ /mnt/nfs nfs auto,ro [summer@bilby ~]$
Beware linewrap.
This mounts a Windows share: mount.cifs \\coco\profile /mnt/coco/ --verbose\ -o \ user=administrator,password=bigfatsecret,ip=10.0.0.253,domain=class.lan
