1052.0. "number of file over 800,000?" by DEKVC::YONGJOONCHOI () Thu Apr 24 1997 05:39

    
    Hi!
    I face very funny situation.
    Alpha Server is running under advfs which  has so many file,directory
    due to  NEWS SERVER(internet).
    The configuration of filesystem is One Domain and 5 filesets and DU is
    4.0b.
    The Capacity of all filesets is under 10%.
    In that case, we can,t not create new file or directory.
    We created file system using mkfdmn default option not using mkfdmn -x
    As following  man page of mkfdmn,the maximun file number 800,000 
    if the BMT extent size 2048. But  file number of our customer site 
    is more than maximun number of files. 
    
    How to do?
    
    thanks

	I can see 2 options 1) Using addvol -x num_pages -p num_pages, add a new device to the domain. Then remove one of the existing devices which will migrate all the files on the device being removed over to the new device which will use larger BMT extents and will have a larger initial BMT to start with. Now use the device just removed and add it back in with a larger -p and -x options, then remove another old device from the domain. Repeat until all the devices with the smaller BMTs have been cycled out and back in again with larger -p & -x values. You may now remove any excess devices. 2) Or vdump the data to tape or another device/filesystem. Recreate the domain using larger -p and -x values. vrestore the data back onto the newly recreated domain. There may be some other approaches and if you search this notes conference you can see what some other people did. Try using one of the internal Alta Vista search engine web pages that catalogs internal notes conferences for a faster search. For example: <http://altavista.notes.lkg.dec.com:8000/> Bob Harris
