how to reformat my SSD (SLOG) with 4k?

Post by Thomymaster »

Hi


I have a SSD which is formatted with 512b blocks rather than with Advanced Format /4k blocks. Ashift shofs a value of 9.
I removed the SSD (ada4) from my zpool, however via the GUi i am unable to reformat it with 4k blocksize.
How can i do that, maybe via CLI?


Cheers
Thomy

no, SLOG and/or SDD always use 512, please google a bit for this topic, is wise discuss.

conclusion your SSD is well if use 512
12.1.0.4 - Ingva (revision 7743) on SUPERMICRO X8SIL-F 8GB of ECC RAM, 11x3TB disk in 1 vdev = Vpool = 32TB Raw size , so 29TB usable size (I Have other NAS as Backup)

ssd need to erase an entire block before writing data to it. this is typically 128kb.

because of this there should be very neglible effect if your drive is not correctly aligned.
Nas4Free 11.1.0.4.4517. Supermicro X10SLL-F, 16gb ECC, i3 4130, IBM M1015 with IT firmware. 4x 3tb WD Red, 4x 2TB Samsung F4, both GEOM AES 256 encrypted.
