Hi, In the first few lines I see the following... 2007-03-29 15:31:06.045: [ OCRRAW][3076419712]propriogid:1: INVALID FORMAT 2007-03-29 15:31:06.046: [ OCRRAW][3076419712]ibctx:1:ERROR: INVALID FORMAT 2007-03-29 15:31:06.046: [ OCRRAW][3076419712]proprinit:problem reading the bootblock or superbloc 22 2007-03-29 15:31:06.049: [ default][3076419712]a_init:7!: Backend init unsuccessful : [22] 2007-03-29 15:31:06.049: [ CSSCLNT][3076419712]clsssinit: error(22 PROC-22: The OCR backend has an invalid format) in OCR initialization I have no idea what that means, I will see if I can find more information. If you know what that means I would appreciate the help. Crs_stat returns CRS-0184: Cannot communicate with the OCR daemon which makes sense (I think) as CRS is not started. I have not looked at ocrdumpo, I will do that.
