XigmaNAS

Hi
I am Nas4free server. (i3-3220, asus P8Z77-V LX, 8Gb memory Kingston NonECC, and 4 hard drive WD Red 2Tb). I have Gigabit Ethernet. Gateway is Mikrotik.
Nas4Free is 9.2.0.1 - Shigawire (revision 972)

I create Raidz-2 array:

zpool status
pool: pool1
state: ONLINE
scan: none requested
config:

NAME STATE READ WRITE CKSUM
pool1 ONLINE 0 0 0
raidz2-0 ONLINE 0 0 0
ada0 ONLINE 0 0 0
ada1 ONLINE 0 0 0
ada2 ONLINE 0 0 0
ada3 ONLINE 0 0 0

errors: No known data errors

And i setup CIFS Share.
cat /vat/etc/smb.conf

I have client Windows 7 Ultimate. Copy speed with Windows 7 to Nas4free very good (70-90 Mbs) but authorization/authentication very slow.
Example:

1. Double click on the icon server --> wait over 30 seconds --> the icon opened
2. Double click on the folder (acces without password) --> wait over 30 seconds --> the folder opened
3. Double clibck on the folder (access with password) --> wait over 30 seconds --> password request

What could be the problem? Why samba is slow work?

Thank for help

8Gb memory Kingston NonECC

First of all, don't run ZFS without ECC RAM. Never!

Yes, I know. I have not other memory.
I installed FreeNAS and ZFSGuru for test. Samba behaves in the same.

work through this

and switch either to UFS or ECC memory, if your data is valuable

Thanks for the answer. This didn't help.
I have two shares.
CommonShare -- without password. Guest access.
ParolShare -- with password. Guest access disabled.

CommonShare opens quickly. But, ParolShare opens very slow. (Windows querying password opens very slow.) I think, the problem is in the authorization. But how can i solve it???

I setup FTP server. Access without anonymous, only local user. Here, athorization is slow. I user GoogleChrome and Filezilla. Filezilla is a little bit faster.

Where there may be a problem??

Dear crowi,

I run ZFS (3x 2T HDDs + 1x640G HDD for system) without ECC ram and the speed is very slow. As per your above advice, I should switch back to UFS. How about Software RAID? Any advices how to switch back to UFS by using these 3 HDDs + 1 system HDD as I don't have spare HDD.

1 system HDD as I don't have spare HDD

Use an USB stick to boot from and install the embedded system.

Converting:
a) Back up your data
b) destroy the ZFS pool
c) re-format the disks to UFS
d) create SoftRAID device
e) restore the data from the backup

Crowi,

I remember it is difficult to destroy ZFS pool as the system will not reformat ZFS disks. Any further instructions to destroy ZFS pools and reformat them? Will Software RAID be better than UFS in speeding the system?

Use in the shell to destroy the pool.

then you can use for each drive to destroy the partitions, following this you can format the drives again.

Not really sure if this might apply but you might try turning off store dos attributes in Samba. It might help but generally this is only if you have lots of files and folders.
