Samba – Security Releases
Mittwoch, August 15th, 2018Samba – Security Releases
Microsoft Windows 10 – a file level backup *.VHD to the NAS device running samba failed
Samstag, April 8th, 2017The failure happens while the *.VHD file created by Windows Backup is mounted during backup. The *.VHD file is created as a sparse file and this is not supported by the native VHD driver and hence mounting of the .*VHD failed. The „strict allocate = yes“ option of Samba will force it to not have UNIX style behavior of creating sparse file
# vi smb.conf
[global]
strict allocate = yes
and enabling SMB Large MTU on Windows Clients

Ingres Database 9.2 – Incremental Rollforwarddb
Dienstag, Februar 10th, 2009The incremental rollforwarddb feature allows the journals from a database to be incrementally applied, as they are generated, to a backup copy of the database. This feature can be used to minimize downtime in the event that the backup database is needed for disaster recovery
Start the incremental rollforwarddb by issuing the following command
# rollforwarddb dbname +c -j -incremental
Issue one or more of the following commands to cause rollforwarddb to discover new journals and apply them
# rollforwarddb dbname -c +j -norollback
The database remains inconsistent and readonly
Discover and apply new journals by issuing the following command
# rollforwarddb dbname -c +j -rollback
The incremental rollforwarddb ends, and the database is marked consistent and updateable
