I thought someone here might have some magic knowledge to help here?
😰 I need help with our workplace’s storage configuration. We require maintaining 90 days of NVR/DVR video footage due to certification standards. Currently, I’m using approximately 128 TB of storage, which allows for a maximum retention period of 89 days and 11 hours. Recently, we experienced a system failure and subsequently added more storage. However, the current block size is 32 KB, which limits our usable storage to 128 TB. To fully utilize our installed 130 TB of storage, I need to increase the block size to 64 KB.
I’m seeking advice on how to:
- Safely copy this data to a temporary location - but where can I copy 128 TB of video footage, without paying a huge sum ? or
- Change the underlying file partition to 64 KB without formatting the drive and losing our existing data.
Does anyone have experience with this type of storage reconfiguration or suggestions?
My thought around this was to format the remaining ~3 TB with the 64 KB block size and repeatedly grow the partition? The DVR records about 3 TB of video a day, but the DVR automagically keeps on recording, and deletes older files at the other end, so kinda stuck how to handle this here?
Worst case is I wipe and start over completely but I would rather not do this because we have unannounced audits, and a failure that prompted the addition of storage in the first place.
