Get ipcshm buf_wait semop errno=43 on Restore

  • 1.  Get ipcshm buf_wait semop errno=43 on Restore

    Posted Mon June 21, 2021 03:46 AM

    Hello,

     

    (Testing/learning purpose.)

    Briefly,

    I have one server IDS 14.10 with demodb database

    And another server with identical disk definition and IDS 14.10 installed.

     

    I made an ontape -s -L 0 on the first server

    Got an archive of 39MB

     

    I copied the archive file to the second server, I changed the name of the archive and tried to restore it on the second one with ontape -p

    And I get in online log:

    09:08:30  Dataskip is now OFF for all dbspaces

    09:08:30  Restartable Restore has been ENABLED

    09:08:30  Recovery Mode

    09:08:32  Physical Restore of rootdbs, dblog started.

     

    09:08:35  Aborting physical restore of ROOT DBSpace

    09:08:35  Aborted by client.

    09:08:35  IBM Informix Dynamic Server Stopped.

     

    And in the shell:

    Continue restore? (y/n)y

    Do you want to back up the logs? (y/n)n

    10:23:05 ipcshm buf_wait semop errno=43

    Physical restore failed - /rootdbs_fs/rootdbs: write failed, file system is full.



    What am i doing wrong ?

    Thanks

    Samuel

    It look likes but it s not

    It s a new install server with same dbspaces size as the primary server and some gigas free on the root filesystem

    Really strange !

    OK, maybe i ll reinstall the server...

    Thanks

    On the target server does Oninit -i work - basically can you get a base engine to run?

    Long shot but check the inodes - df -h will not show a FS out of inodes.

    If you have lsof see if there are any orphaned processes holding on to space in the FS

    Hi

    Yes, the oninit -i worked


    ids-hdr:/IDS/informix$oninit -i

    This action will initialize IBM Informix Dynamic Server;
    any existing IBM Informix Dynamic Server databases will NOT be accessible -
    Do you wish to continue (y/n)? y
    ids-hdr:/IDS/informix$onstat -

    IBM Informix Dynamic Server Version 14.10.FC4W1 -- On-Line -- Up 00:00:17 -- 165416 Kbytes

    ids-hdr:/IDS/informix$


    And after the install i shut down the server and try to restore and now i have system full on /dblog_fs/dblog (instead of roodbs)

    online.log

    Could you provide more info - e.g.

    OS on both servers; df on both servers; ipcs on both servers; ls -l /dblog_fs on both servers

    Hello Hrvoje Zokovic

    This problem is solved.
    I was really a problem of disk space, even if the two virtual machines (source and destination) were configure the same way.

    One machine was Centos 7 and the second one Rocky Linux 8

    I apparently did something wrong and i don't know what.
    It s not so important because it was only for testing.

    I increased the size of the destination VM (virtualbox) disks and it worked.

    Thanks a lot
    Samuel
