I've a ReadyNAS 104 updated with latest OS (6.2.4). Yesterday, after a power loss (my dad turned off the UPS :roll: ) the NAS took 12 hour (after turned off all the apps, and fine-tuned some resync parameters otherwise the estimated time could be about 24 hours) to resync the 3 disks that form the (X-RAID) volume that I use for my backups. No data was lost. But I've seen that the RAID volume don't uses the write-intent bitmap. I guess that is disabled by default to not impact write performance. But except for the impact on write performance there is any other specific reason to keep the write-intent bitmap disabled? Because I might prefer to sacrifice some writing performance if this can drastically reduce the resync time when my dad... ehm... when the NAS is not shut down safely.
