Summary0002115: 2.3/Rev 3029 Session Raid (version was not available in Product Version)
DescriptionI am trying to get Soft Raid/Session Raid working. It seemed like i had it working <1.0 but it's been a long time. I have two identical 160 gig SATA drives (listed below as data and data2) for Ardour data only. The OS and /home are on two additional IDE drives.

/data and /data2 both have an /ardour dir created. In Windows | Preferences | Paths/Files | Session Raid Path I currently have:


It seems that the usual Ardour directories are created only in path specified in the:

New Session | Create folder in

dialog. In the path example above I eventually manually added a second directory of /split_test after the first one was created with New Session.

I have tried with and without trailing /

After finding this (old?) ardour manual at

I tried the suggestions there. From that page:
Ardour’s “Soft” RAID Path

It is possible to spread the resources for your Ardour session across multiple disks. This can increase the number of tracks or regions you can work with at once.

There is no reason to do this if your computer has only one disk.

To use the “soft RAID” feature, manually create a new directory on another disk. Open the Options Editor window. Click on the Paths/Files tab. In the “session RAID path” text box, you will see that the default value is the path to the directory where your current session lives. But this Session RAID Path can actually be a colon-separated list of directories. To add your new directory to this list, type a single colon after the existing Session RAID Path, followed by the full path to the new directory. Ardour will now record new tracks to either directory. (question: how does ardour decide which files go where?)

You can squeeze some more disk performance out of an existing session by following the above procedure, then manually moving some files from the sounds/ subdirectory of the existing session into a sounds/ subdirectory of your new directory. Be very careful when doing this! If you accidentally delete these sound files, Ardour cannot magically fix it for you.

The /sounds directory as listed above does not exist in current versions, I manually created a dir named:


where the wav files are. I moved half of them over to the other disk. When I load the session, half of the tracks are missing audio. I manually added the new path to the dialog in Windows | Preferences | Paths/Files | Session Raid Path but the other half of the files do not appear.

Ardour's log says:

ERROR]: Filesource: cannot find required file (Audio 4-4.wav): while searching /media/data/ardour/split_test/interchange/split_test/audiofiles
[WARNING]: A sound file is missing. It will be replaced by silence.

I also tried adding this to ardour.rc :

<Option name="session-path" value="/media/data/ardour:/media/data2/ardour"/>

No success, but Ardour otherwise seemed to run normally.
