Hi,
I would appreciate comments/confirmation relative to replacing a failed single drive with larger hard disk.
I am running FreeNAS-11.2-U5 on a Dell T20 with four 3TB WD Red drives in a raidz2 configuration. Last night, I received an alert saying that my main pool’s state was degraded and one drive had been removed by the administrator.
I pulled that disk this morning and the Western Digital diagnostics found the drive has lot of bad sectors. Unfortunately, it is 4 months past the warranty. :(
Instead of replacing this drive with another 3TB drive, I am wondering if I should go to something a bigger.
If I understand some other postings and the user’s manual correctly, the smallest drive in a volume dictates the available size of the volume. So even if I replaced the bad drive with a 6TB drive, the volume’s available size wouldn’t change until the other 3 drives where replaced with larger drives.
I am thinking that as the remaining drives fail, I could replace the failed drive with 6TB drives. Then once the last drive is replaced and the resilvering is complete, the available size of my volume would basically double from 5.1TB to 10.2TB.
I would appreciate if one of the experts on this forum would correct/confirm my understanding on this.
Thanks in advance, Paul
