Replace failed disk in raid

Hello list
A disk, part of a raid failed and I have to replace it.
My problem is the swap partition which is in raid0. The rest partitions
are in raid1 and I successfully removed them.
The partition in swap cant removed because is probably active.
How can I stop swap and remove partition?
After replacing the faulty disk and rebuilt how I start swap again?

fail2ban problem

Hello list
I'm trying to setup fail2ban specially sasl action but I'm facing problems.
I have centos-release-5-9.el5.centos.1
with selinux disabled

The errors I get are:
INFO Creating new jail 'sasl-iptables'
fail2ban.comm : WARNING Invalid command: ['add', 'sasl-iptables',

I tried gemin against polling but I get the same error.
The strange thing is that if I enable ssh action, starts with no problem.
So it appears to be problem with sasl action, witch is:


enabled = true
filter = sasl
backend = polling
action = ip

Limit max number of e-mails sent per hour

Hello list
I use sendmail-8.14.4-8.el6.x86_64 and I wonder how to restrict the
number of emails sendmail sent over an hour.
Is the define(`confMAX_QUEUE_RUN_SIZE', `200') command what I'm looking for?
Thank you in advance.

fail2ban help

Hello list.
I have a question for fail2ban for bad logins on sasl.
I use sasl, sendmail and cyrus-imapd.
In jail.conf I use the following syntax:


enabled = true
filter = sasl
backend = polling
action = iptables[name=sasl, port=smtp, protocol=tcp]
sendmail-whois[name=sasl, dest=my@email]
logpath = /var/log/maillog
maxretry = 6

and the following filter:

failregex = (?i): warning: [-._\w]+\[<HOST>\]: SASL
(?:LOGIN|PLAIN|(?:CRAM|DIGEST)-MD5) authentication failed(:

in iptables:

fail2ban-sasl tcp -- anywhere anywhere
