Hi everyone,
we have a promise pegasus R6 with 6 drives à 1 TB so 6 TB in total. The info panel for the locgical drive is showing:
Capacity: 5 TB
Physical Capacity: 6 TB
Since we use the Raid as backup and it happened to be full we would like to use this 1 TB as well. Can anyone help?
Best,
Tim
PS. We are planning to replace all drives in the future …
Hey Arun,
thanks for your help. We already ordered new 3 TB disks in order to replace the existing ones :).
I assume this also is done by creating a new array, right?
Thanks again and best regards,
Tim
Hi Tim,
Pegasus have default RAID 5 configuration.RAID 5 is data striping with parity.It has one HDD fault tolerance(No data lost if single drive failure).The usable capacity in RAID 5 is Total HDD capacity subtract to one HDD capacity.i,e 6TB-1TB=5TB
If you still want to use total physical capacity 6TB ,you could backup the data from the drive ,delete and recreate the RAID choosing RAID 0 .But, it is not recommended as RAID 0 is disk striping without data redundancy(Data lost if single drive failure)
Please find the below KB article link for how to create new RAID

Please let me know if you have any queries
Regards
Arun
