Splitfilesystem

Splitfilesystem

Currently there are three different Versions with different features available. Splitfilesystem and SplitfilesystemV2 are in maintanace mode and can still be used in existing installations. For new installations or repositories SplitfilesystemV3 is recommended.

SplitfilesystemV3 (from tia ContentServer 3.6.0 or newer)

Example:

<repo>.contentservice.type     = splitfilesystemv3
<repo>.description             = Finance Repository
<repo>.saphttp.security        = 1
<repo>.accessmode              = rucd
<repo>.authentication.required = false
<repo>.authentication.user     = 
<repo>.authentication.pwdalias = 

#===== FI content service configuration (filesystem|splitfilesystemv2|splitfilesystemv3|azureblobstore|s3blobstore|kgsstore)
<repo>.contentservice.splitfilesystemv3.root.1 = C:/Doc_Base
<repo>.contentservice.splitfilesystemv3.root.2 = C:/Doc_Base_Disk2
<repo>.contentservice.splitfilesystemv3.contrepinpath = true
<repo>.contentservice.splitfilesystemv3.maxfolderblocks=8
<repo>.contentservice.splitfilesystemv3.maxFileNameLength=200
<repo>.contentservice.splitfilesystemv3.rootSelectionIntervalH=24

To use the splitfilesystemv3 the <repo>.contentservice.typeneeds to be splitfilesystemv3.

All parameters for splitfilesystemv3 must be configured within <repo>.contentservice.splitfilesystemv3 on a repository or template level.

root folder selection rules

Multiple root directories are allowed in SFSV3 to spread repositories across different disk/shares and avoid limit of filesystems.
Multiple roots can be configured distinguished by a ordernumber. e.g. root.1,root.2

• the algorithm tries in numbers order to pick the root

  • it checks the available space and compares it with the given limit. Default limit is -1.

  • If the algorithm finds out, that a root hasn’t enough space it tries the next.

  • with limit -1 a drive can be blocked. The space detection is skipped. It is then used in read only state (and / or only for adding components and infos)

    • if the last root has -1 it will be written until IOEXCEPTION, means the root is “full“

• the algorithm is triggered by:

  • if rootSelectionIntervalH is exceeded

  • if IOException had happen while IO operation

Example:

<repo>.contentservice.splitfilesystemv3.root.1 = C:/Doc_Base
<repo>.contentservice.splitfilesystemv3.root.2 = C:/Doc_Base_Disk2
<repo>.contentservice.splitfilesystemv3.root.2.freespacegb=-1
<repo>.contentservice.splitfilesystemv3.root.3 = C:/Doc_Base_Disk3
<repo>.contentservice.splitfilesystemv3.root.3.freespacegb=10
<repo>.contentservice.splitfilesystemv3.root.4 = C:/Doc_Base_Disk4
<repo>.contentservice.splitfilesystemv3.root.4.freespacegb=50

In this example root.1 is skiped and only used for reading because freespacegb is not set and therefore -1.

root.2 is also skipped because freespacegb is -1.

root.3 is only used when C:/Doc_Base_Disk3 has more than 10 GB available space.
root.4 is only used when C:/Doc_Base_Disk4 has more than 50 GB available space.
Is root.3 and root.4 disk space exceeded storing documents is no longer possible only reading.

Be aware that SFSV3 tries to keep documents in same folder together, when a document is stored in the original root and later a second document or component should be added in the same folder even when root.4 is used at the moment, SFSV3 will store the document in root (C:/Doc_Base). Make sure that your not used disk have some space left otherwise modification is no longer possible.

SplitfilesystemV2

The files are stored within a filesystem in Base32 coded structures. The whole path is base 32 coded and divided into blocks.

C:\Doc_Base\FI\FZVW\O4Y\OJQX\O\GIYD\EMZQ\G4YT\GXZW\GEYW\GZJQ\G44C\2MRZ\GE2S\2NBS\GNSC\2OBR\HEYC\2YZX\GJSD\IMBT\GM3W\MZRZ\L5XG

The metadata and properties of the archived document are stored in a .info-File as JSON.
