Backup Central

I'm running Amanda 3.1.2 on Solaris 10x86, client is not server
but both platforms are same OS and Amanda version.

To correct this error

amcheck -c curie finsen

Amanda Backup Client Hosts Check
--------------------------------
ERROR: finsen: service selfcheck: selfcheck: error [open pipe to /usr/local/libexec/amanda/application/amzfs-snapshot: Too many open files]
ERROR: finsen: service /usr/local/libexec/amanda/selfcheck failed: pid 3008 exited with code 1
Client check: 1 host checked in 201.322 seconds. 2 problems found.

(brought to you by Amanda 3.1.2)

I'm trying to increase the number of file descriptors avaiable to
the amanda processes on the client.

Recognizing that amanda processes do not invoke the shell and
will not execute .cshrc, I am trying to increase the file limit
by modifying resource controls.

[finsen/export/home] cat /etc/project
system:0::::
user.root:1::::
noproject:2::::
default:3::::
group.staff:10::::
user.amanda:10080:Amanda Daemons:amanda::process.max-file-descriptor=(basic,8192,deny)

This seems to be fine for interactive processes

id
uid=110(amanda) gid=3(sys)

plimit $$
5292: -tcsh
resource current maximum
time(seconds) unlimited unlimited
file(blocks) unlimited unlimited
data(kbytes) unlimited unlimited
stack(kbytes) 10240 unlimited
coredump(blocks) unlimited unlimited
nofiles(descriptors) 8192 unlimited
vmemory(kbytes) unlimited unlimited

But this is the shell.

When we check the daemon we see a different story.

[finsen/root] plimit 26084
26084: /usr/local/libexec/amanda/selfcheck amandad bsdtcp
resource current maximum
time(seconds) unlimited unlimited
file(blocks) unlimited unlimited
data(kbytes) unlimited unlimited
stack(kbytes) 10240 unlimited
coredump(blocks) unlimited unlimited
nofiles(descriptors) 256 65536
vmemory(kbytes) unlimited unlimited

I'm unclear as to how to increase this limit for the amandad
daemon as started by inetd.

Clearly I'm missing a step but I'm not finding the right docs.

thanks,

Brian

oh!

We have 277 DLEs on this client, the file decriptor limit is 255.

I wonder if its enough to try and ammend the perl code to include
/usr/bin/ulimit or the mod needs to be higher up in the code.

ERROR: finsen: service selfcheck: selfcheck: error [open pipe to /usr/local/libexec/amanda/application/amzfs-snapshot: Too many open files]
ERROR: finsen: service /usr/local/libexec/amanda/selfcheck failed: pid 28870 exited with code 1

The same code that created the snapshot destroys it, right ?

Jon had a good idea in using tcp_wrappers to up the limit but
I haven't had any luck implementing it. Has anyone used home grown
tcp_wrappers on Solaris 10 ?

thanks,

Brian

just as a check, how about wrapping amcheck in a script.

move amcheck to amcheck.real

install a 2 line script as amcheck

<command to up the descriptor limit>
exec <path_to_amcheck.real> "$ < at > "
