Hi everyone,
Haven't been here for a while.
Have a strange question , maybe?
I have a Proxmox 5.4 server setup on ZFS.
The setup is as follows:
A system is on 2 SSD in mirrored pool
And around 16 HDDs of various sizes in mirrored pools based on disks size. Like I have a pool with 2T disks. A pool with 3T disks and pool with 4T disks.
All HDD based pools are for data storage.
Now last week I found that one of the SSDs failed. The rpool was running in degraded mode.
The initial setup was on 120gb SSD.
I ordered several 240gb SSDs to replace. I swap the failed with new , did all the partition copy from a good one, id randomise and DD the boot grab.
Added to the pool, it resilvere and reboot. All is good so far as I did not test the bootabiluty of new drive yet.
My question is this, since the new drive is larger, it make sense to swap the other disk to. But should I expand the pool size after.
I read some where that if you use zfs on SSD you can size the pool so it does not use all the space on the disk and leave that space for wearleveling this prolonging the disk life. Is it true?
Should I do it this way.
My disks are not Enterprise.
They are Soho.
This is the new disks
Inland Professional 240GB SSD 3D NAND SATA III 6Gb/s 2.5" 7mm Internal Solid State Drive
Thanks.
