Problem

If you did the upgrade to Checkmk 2.0 and are using the old Service descriptions, you need to migrate this manually.

Solution

...

1. We need to find all the rrd files with fs_*

   Code Block
   language bash theme RDark
   OMD[mysite]:~$ for i in $(find . -type f -name "fs_*"); do echo $i; done ./var/check_mk/rrd/mywindowshost/fs_C__.rrd ./var/check_mk/rrd/mywindowshost/fs_C__.info ./var/check_mk/rrd/mylinuxhost/fs__boot_efi.info ./var/check_mk/rrd/mylinuxhost/fs__media_linuxhost_SDCard.rrd ./var/check_mk/rrd/mylinuxhost/fs__boot.info ./var/check_mk/rrd/mylinuxhost/fs__media_linuxhost_USB.rrd ./var/check_mk/rrd/mylinuxhost/fs__opt_omd_sites_mysite_tmp.rrd ./var/check_mk/rrd/mylinuxhost/fs__.rrd ./var/check_mk/rrd/mylinuxhost/fs__media_linuxhost_USB.info ./var/check_mk/rrd/mylinuxhost/fs__boot.rrd ./var/check_mk/rrd/mylinuxhost/fs__media_linuxhost_SDCard.info ./var/check_mk/rrd/mylinuxhost/fs__opt_omd_sites_mysite_tmp.info ./var/check_mk/rrd/mylinuxhost/fs__.info ./var/check_mk/rrd/mylinuxhost/fs__boot_efi.rrd ./var/check_mk/rrd/mylinuxhost/fs__boot_efi.info ./var/check_mk/rrd/mylinuxhost/fs__media_linuxhost_SDCard.rrd ./var/check_mk/rrd/mylinuxhost/fs__boot.info ./var/check_mk/rrd/mylinuxhost/fs__media_linuxhost_USB.rrd ./var/check_mk/rrd/mylinuxhost/fs__opt_omd_sites_mysite_tmp.rrd ./var/check_mk/rrd/mylinuxhost/fs__.rrd ./var/check_mk/rrd/mylinuxhost/fs__media_linuxhost_USB.info ./var/check_mk/rrd/mylinuxhost/fs__boot.rrd ./var/check_mk/rrd/mylinuxhost/fs__media_linuxhost_SDCard.info ./var/check_mk/rrd/mylinuxhost/fs__opt_omd_sites_mysite_tmp.info ./var/check_mk/rrd/mylinuxhost/fs__.info ./var/check_mk/rrd/mylinuxhost/fs__boot_efi.rrd

   .

2. We need to rename all these files from fs_* to Filesystem_:
   
   

   Warning
   Caution: This is the most dangerous step.

   
   

   Code Block
   language bash theme RDark
   OMD[mysite]:~$ for i in $(find . -type f -name "fs_*"); do sed -i "s/SERVICE fs_\(.*\)/SERVICE Filesystem \\1/" $i; mv "$i" "$(echo "$i" |sed s/fs_/Filesystem_/)"; done

   .

3. Let's check if it worked

   Code Block
   language bash theme RDark
   OMD[mysite]:~$ for i in $(find . -type f -name "fs_*"); do echo $i; done No results for fs_* OMD[mysite]:~$ for i in $(find . -type f -name "Filesystem_*"); do echo $i; done ./var/check_mk/rrd/mywindowshost/Filesystem_C__.info ./var/check_mk/rrd/mywindowshost/Filesystem_C__.rrd ./var/check_mk/rrd/mylinuxhost/Filesystem__boot.rrd ./var/check_mk/rrd/mylinuxhost/Filesystem__.info ./var/check_mk/rrd/mylinuxhost/Filesystem__media_linuxhost_SDCard.rrd ./var/check_mk/rrd/mylinuxhost/Filesystem__boot_efi.info ./var/check_mk/rrd/mylinuxhost/Filesystem__boot_efi.rrd ./var/check_mk/rrd/mylinuxhost/Filesystem__opt_omd_sites_mysite_tmp.info ./var/check_mk/rrd/mylinuxhost/Filesystem__opt_omd_sites_mysite_tmp.rrd ./var/check_mk/rrd/mylinuxhost/Filesystem__media_linuxhost_USB.rrd ./var/check_mk/rrd/mylinuxhost/Filesystem__.rrd ./var/check_mk/rrd/mylinuxhost/Filesystem__media_linuxhost_USB.info ./var/check_mk/rrd/mylinuxhost/Filesystem__boot.info ./var/check_mk/rrd/mylinuxhost/Filesystem__media_linuxhost_SDCard.info ./var/check_mk/rrd/mylinuxhost/Filesystem__boot.rrd ./var/check_mk/rrd/mylinuxhost/Filesystem__.info ./var/check_mk/rrd/mylinuxhost/Filesystem__media_linuxhost_SDCard.rrd ./var/check_mk/rrd/mylinuxhost/Filesystem__boot_efi.info ./var/check_mk/rrd/mylinuxhost/Filesystem__boot_efi.rrd ./var/check_mk/rrd/mylinuxhost/Filesystem__opt_omd_sites_mysite_tmp.info ./var/check_mk/rrd/mylinuxhost/Filesystem__opt_omd_sites_mysite_tmp.rrd ./var/check_mk/rrd/mylinuxhost/Filesystem__media_linuxhost_USB.rrd ./var/check_mk/rrd/mylinuxhost/Filesystem__.rrd ./var/check_mk/rrd/mylinuxhost/Filesystem__media_linuxhost_USB.info ./var/check_mk/rrd/mylinuxhost/Filesystem__boot.info ./var/check_mk/rrd/mylinuxhost/Filesystem__media_linuxhost_SDCard.info OMD[mysite]:~$

   .

4. Now we need to change the service description in the global settings:
   
   Setup → General → Global Settings → Use new service descriptions → Used space in filesystems
   

   .

5. Please follow the instructions here
   .

6. Now you should see the new Services in Checkmk with your old historic data:
