Hello Bruno Sorry to bother you again. Have you got any idea why size computation works great for all LVs in linuxvg but not for the LVs in backupvg and testvg? Your tool is really great and it would be perfect for me if I could also backup additional VGs/LVs. Is there a switch to backup the VGs/LVs in PEs then using the computation in MB? Do I have to consider something when creating additional LVs that size computation works fine? Regards, Manuel Manuel Laesser wrote: > Hello Bruno > Thank you very much for your answer. You're right.
