MogileFS on Debian Lenny

[rajan chandi]

Hi All,

I am trying to set up a basic MogileFS and have trackers and storage server on the same machine.

When I try to check the stuff
mglfs1_srv:/var/mogdata# mogadm --lib=/usr/local/share/perl/5.10.0/ --trackers=127.0.0.1:6001 check
Checking trackers...
  127.0.0.1:6001 ... OK

Checking hosts...
  [ 1] mogilestorage ... OK

Checking devices...
  host device         size(G)    used(G)    free(G)   use%   ob state   I/O%
  ---- ------------ ---------- ---------- ---------- ------ ---------- -----
  [ 1] dev1   REQUEST FAILURE
  ---- ------------ ---------- ---------- ---------- ------
             total:     0.000      0.000      0.000   0.00%

The Device is not working properly.

Any ideas/pointers will help.

Thanks and regards
Rajan Chandi

Can you connect manually to the mogstored? Both the HTTP and admin
ports? You do have a device at the dev1 point of mogstored that you
set up?

Yes, I did add the device myself using this.
mogadm --lib=/usr/local/share/perl/5.10.0/ --trackers=127.0.0.1:6001 device add mogilestorage 1

It does connect but seems to be doing nothing.
mglfs1_srv:/var/mogdata# telnet 127.0.0.1 7500
Trying 127.0.0.1...
Connected to 127.0.0.1.
Escape character is '^]'.
PUT /dev1/test HTTP/1.0

No, I mean the physical storage behind it. Does the usage file get
written? Usually at /var/mogdata/$DEV/usage.

That command only tells Mogile about the device.

[rajan chandi]

Not really. I don't see the usage file being created.

mglfs1_srv:/var/mogdata# ls -a
.  ..  dev1

mglfs1_srv:/var/mogdata/dev1# ls -a
.  ..

Can I write this manually? The mogstored and mogilefs processes are running but may be some issue!

Thanks and regards

Those files should be written by mogstored - check directory permissions for user under which you run mogstored.

I seem to have 3 users.
mglfs1_srv:/home# ls
mogile    mogilefsd  mogstored

Now, I executed:-
mglfs1_srv:/var# chmod -R 777 mogdata

restarted my machine. Is there any other way to restart mogstored?

This Fixed the error :)

mglfs1_srv:~# mogadm --trackers=127.0.0.1:6001 device list
mogilestorage [1]: alive
                   used(G) free(G) total(G)
  dev1: alive      1.129   185.732 186.861

It doesn't sound work all right!

mglfs1_srv:~# telnet 127.0.0.1 7500

Trying 127.0.0.1...
Connected to 127.0.0.1.

I actually could add domain and a class...but it doesn't let me telnet and do HTTP PUT there!

mogadm --lib=/usr/local/share/perl/5.10.0 --trackers=127.0.0.1:6001 domain add hpdomain
mogadm --lib=/usr/local/share/perl/5.10.0 --trackers=127.0.0.1:6001 class add hpdomain testclass

May be I am missing something.

Thanks in advance.

Rajan

No, do NOT do this.
Find out what user mogstored is running as, and chown -R the mogdata
directory to it. Then lock it back down.
EG:
# chown -R mogstored /var/mogdata/
# chmod -R go-rwX /var/mogdata/

I don't know what init scripts Debian packages with their Mogile.
Consult your package manager.

Try to use mogtool instead of telnet.
If that fails, go and poke at mogstored's debug logging.

I'm headed to bed, so no more responses from me for the next 10 hours.

[rajan chandi]

Thanks. I made it more secure. I will try out mogtool. Thanks again.

[rajan chandi]

Mogtool helped. Thanks a lot Robin.
