I want to do zfs clone of folder in a ZFS pool. Can I place this clone in RAM or on RAMDISK? I want to do this, because I want to write clone changes in RAM (for speed optimization).
P.S. Sorry for my russian-english...:r
1. Yes, I mean 64KB block size NTFS;
2. Why iSCSI? because:
- iSCSI fastest net protocol;
- iSCSI target I can connect like natural Hard Disk (in samba just mapped net disk);
- I can boot PC without HDD from iSCSI target in lan;
3. Please answer to me for question:
- If iSCSI target on the...
THank you for your answer!
The NEXT noob's question:
1. Created iSCSI target;
2. Formated from iSCSI initiator to NTFS (64KB);
All my writes from iSCSI initiator to iSCSI target will be under 64KB in size? All in ZiL first?
Sorry for noob qestion, but Write-Back cache - it exists in zfs/FreeBSD? what is his correct name? ZiL? P.S. for example: LARC and L2ARC - are caches for read :) P.S.S. Sorry for my russian-english :stud
I have read that ZFSv18 and older cannot import a pool with a failed log vdev. Thus, all log vdevs must be created as mirrors...
This means that when during a long time of not having any commands to the write, the ZiL is completely empty?
P.S. Sorry for my russian-english language ^)
Hello!
Please tell me how does ZiL work in ZFS? L2ARC works as a READ cache layer in-between main memory and Disk Storage Pool. It holds non-dirty ZFS data, and is currently intended to improve the performance of random READ workloads or streaming READ workloads (l2arc_noprefetch option)...
