Long time user just upgraded yesterday from 2.4.5 to 2.5.0 and having major problems:

zenactions spewing errors:

So I thought maybe a zendmd and reindex() would be in order but I can't even run zendmd (running as user zenoss of course):

I have stopped all zenoss processes, deleted /opt/zenoss/var/*zec* -- no luck.

Any help much appreciated.

Re: Issues with 2.5.0

Seems to be that you have the same problem after upgrading. Check thread/11846?tstart=0

Re: Issues with 2.5.0

Ok. I'll focus on the issue of zendmd not running (I'd like to be able to do a Zope reindex()). I edited/opt/zenoss/lib/python/ZODB/lock_file.py and commented out the try/except so I could see the error that flock was raising:
    def _lock_file(file):
        #try:
        fcntl.flock(file.fileno(), _flags)
        #except IOError:
        #    raise LockError("Couldn't lock %r" % file.name)

restart zenoss, ran zendmd
and got this:
[some stuff deleted]

    fcntl.flock(file.fileno(), _flags)
IOError: [Errno 11] Resource temporarily unavailable

So, another process has hold of the lock file.

$ lsof /opt/zenoss/var/zeo1-1.zec.lock
COMMAND   PID   USER   FD   TYPE DEVICE SIZE   NODE NAME
python 22439 zenoss    8uW REG 253,0    0 756266 /opt/zenoss/var/zeo1-1.zec.lock

[Edit: For clarification, below is the process information for the above pid (22439) returned by lsof]

0 S zenoss   22439 22437 2 76   0 - 26769 -      09:52 ?        00:00:05 /opt/zenoss/bin/python /opt/zenoss/lib/python/Zope2/Startup/run.py -C /opt/zenoss/etc/zope.conf

It's zope's run.py. Should that run.py be holding on to this lock? I'm confused and not sure what's changed. Can others run zendmd OK in 2.5.0?

Re: 2.5.0 - zendmd won't run

Anyone have any ideas on what's causing the EAGAIN lock error ("Resource temporarily unavailable") error when I try to run zendmd? (described in previous post)

Re: 2.5.0 - zendmd won't run

If you had the WMI Data Source ZenPack installed when you upgraded then that's your issue. If not, then I'm not sure what's causing that.

Re: 2.5.0 - zendmd won't run

No, I don't have that zenpack installed. I haven't heard of anyone else having the problem with zendmd not running because it can't lock the file that zope has a lock on. I've never had this problem before. I wonder how many people have even tried to run zendmd with 2.5.0 yet.

Re: 2.5.0 - zendmd won't run

I've used zendmd with 2.5 on numerous occasions and have not come across any issues. You might want to check your file permissions in your $ZENHOME directory.

Re: 2.5.0 - zendmd won't run

I'm glad to hear that zendmd works in 2.5.0

I think my perm's are good:
[zenoss:/opt/zenoss]$ pwd
/opt/zenoss
[zenoss:/opt/zenoss]$ ls -lad . var var/zeo1-1.zec.lock
drwxr-xr-x 26 zenoss zenoss 4096 Nov 2 10:36 .
drwxrwxr-x   7 zenoss zenoss 4096 Nov 2 10:35 var
-rw-rw-r--   1 zenoss zenoss    0 Nov 2 12:44 var/zeo1-1.zec.lock

Would you mind checking on your system like I've done below to see if Zope has a lock on this file like mine does:
[root:~]# lsof /opt/zenoss/var/zeo1-1.zec.lock
COMMAND   PID   USER   FD   TYPE DEVICE SIZE   NODE NAME
python 22439 zenoss    8uW REG 253,0    0 756266 /opt/zenoss/var/zeo1-1.zec.lock
[root~]# ps wp 22439
PID TTY      STAT   TIME COMMAND
22439 ?        Sl    30:21 /opt/zenoss/bin/python /opt/zenoss/lib/python/Zope2/Startup/run.py -C /opt/zenoss/etc/zope.conf

I appreciate your help and input.

Re: 2.5.0 - zendmd won't run

I found a workaround on the issue of zendmd not running b/c of zope having file locked (here's the pertinent error message again for those interested):
2009-11-06 09:14:52 ERROR ZODB.lock_file Error locking file /opt/zenoss/var/zeo1-1.zec.lock; pid=UNKNOWN

I was able to run zendmd if I stopped Zope first. Got my reindex and commit done and now all my daemons are starting. Seems healthy for the moment.

I can live with this workaround.

Re: 2.5.0 - zendmd won't run

I see a simple fix was recently posted to your ticket (http://dev.zenoss.org/trac/ticket/5798)
I changed the zope.conf per the instructions and now I can run zendmd just fine while zope is running.

All better!!
