>From: Paul Prestopnik <address@hidden> >Organization: NCAR/RAL >Keywords: 200512122354.jBCNsl7s024279 LDM large queue Hi Paul, Missing from the information you included was what kind of hardware you are using and what Operating System you are running (I assume Linux, but we need more information). Please send the output of the following: uname -a cat /proc/cpuinfo LDM queues larger than 4 GB can be build on Linux systems that are running on 64-bit hardware (e.g., AMD Opteron and Athlon 64 or Intel Xeon EM64T) and are running the 64-bit version of the operating system. As soon as we determine that your system meets these criteria, we can help you create a large LDM queue. Cheers, Tom Yoksas >When we run the ldmadmin pqcreate -f option we get this error: > >> ldmadmin mkqueue -f >Dec 12 23:48:37 pqcreate[2474] ERROR: ctl_init(): Data portion of file is too > big for one region >pqcreate: create "/home/ldm/data/ldm.pq" failed: File too large >Dec 12 23:48:37 UTC awl.rap.ucar.edu : make_pq: mkqueue failed > >Here are the values in our ldmadmin-pl.conf file: >> ldmadmin config > >hostname: awl.rap.ucar.edu >os: Linux >release: 2.6.12-ral-smp >ldmhome: /home/ldm >bin path: /home/ldm/bin >conf file: /home/ldm/etc/ldmd.conf >log file: /home/ldm/logs/ldmd.log >numlogs: 7 >log_rotate: 1 >data path: /home/ldm/data >product queue: /home/ldm/data/ldm.pq >queue size: 10G bytes >queue slots: default >IP address: all >port: 388 >PID file: /home/ldm/ldmd.pid >LDMHOSTNAME: awl.rap.ucar.edu >PATH: /home/ldm/bin:/bin:/usr/bin:/usr/sbin:/sbin:/usr/ucb:/usr/usb:/ > usr/etc:/etc:.:/home/ldm/bin:/home/ldm/util:/home/ldm/decoders:/home/ldm/rap/ > bin:/home/ldm/decoders:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbi > n:/bin:/usr/bin/X11 > > >Top shows that we have 12G of ram: > >top - 16:51:04 up 10 days, 38 min, 2 users, load average: 0.06, 1.26, 1.14 >Tasks: 83 total, 1 running, 82 sleeping, 0 stopped, 0 zombie >Cpu(s): 0.0% us, 0.0% sy, 0.0% ni, 99.5% id, 0.5% wa, 0.0% hi, 0.0% si >Mem: 12474024k total, 4345580k used, 8128444k free, 182620k buffers >Swap: 4200988k total, 0k used, 4200988k free, 112500k cached > > >And df shows that we have 17G of space on /d1 >> df -h >Filesystem Size Used Avail Use% Mounted on >/dev/sda1 4.0G 1.5G 2.3G 39% / >tmpfs 6.0G 4.0K 6.0G 1% /dev/shm >/dev/sda5 4.0G 142M 3.7G 4% /var >/dev/sda6 4.0G 44M 3.8G 2% /home >/dev/sda7 18G 37M 17G 1% /d1 >linux:/exports/linux-i386 > 118G 43G 70G 38% /var/autofs/mnt/linux-i386 > >note that ~ldm/data points to /d1/ldm/pq/ > >awl:~> ll ~ldm/data >lrwxrwxrwx 1 ldm ldm 10 Dec 5 14:36 /home/ldm/data -> /d1/ldm/pq/ > > >We would like to build a 10G queue, but we can't get one to succesfully build >for sizes greater than 4G. > >-Paul Prestopnik > > -- NOTE: All email exchanges with Unidata User Support are recorded in the Unidata inquiry tracking system and then made publicly available through the web.
