Why can't the EonNAS Finder utility detect my EonNAS system?
It might take several seconds before the Finder utility detects your system. If the system still does not appear after waiting several seconds, please try disabling the Firewall on your client to allow your EonNAS system to be detected.
Why has the disk size of the EonNAS system been reduced after the RAID configuration has been completed?
When configuring two disks as RAID 1, the usable disk size equals the size of one disk.
When configuring N disks as RAID 5, the usable disk size equals the size of (N-1) disk(s).
When configuring N disks as RAID 6, the usable disk size equals the size of (N-2) disk(s).
Are there any limitations for the username and password settings?
Username must contain 19 characters or less; password must contain 32 characters or less.
What are the valid characters for the system username?
Numbers 0 through 9, letters a through z and capitalized letters A through Z. Moreover, the first character of the username cannot be a number.
What's the maximum length of the EonNAS system name?
Is it necessary to defragment the internal hard drive of the EonNAS system?
No, this is not necessary. EonNAS uses the ZFS file system. Unlike FAT and NTFS, ZFS can avoid file fragmentation.
What's the default username and password?
Default users name and password are both "admin".
Can the EonNAS system partition hard drives?
No. The internal hard drive of EonNAS is formatted and initialized according to the software design.
What should be done when the disk access rate becomes very slow?
- Restart the EonNAS system.
- Check the current disk settings and status information. If the system has experienced a hard disk failure, repair it ASAP.
- Check if other devices for network access have the same problem. If the internal network is not functioning properly (e.g. PCs are infected), contact technical support teams.
- When disk data is being accessed by a large number of applications/users, or when replication is being conducted, disk access will become slower due to the heavy workload of the EonNAS system. You may try to access later.
I forgot my IP address setting. How can I find the IP address of the EonNAS system?
Run EonNAS finder to discover your EonNAS system.
Can users in different network domains configure the same EonNAS as a network disk drive?
Yes. To access an EonNAS system by its server name, make sure there is a WINS server in your network and the service is enabled. If not, you can access the server via the EonNAS IP.
Can I upgrade the memory of my EonNAS system?
Yes, you can. But you can only install memory bought from Infortrend and you need to first check the upgrade path with our sales representatives.
Can I configure multiple RAID groups of different RAID levels in a single EonNAS system?
Yes, you can configure multiple RAID groups as either a single pool or as multiple pools in the system.
What should be done when a disk error is detected in a RAID 1/5/6 configuration?
Take out the failed drive and replace (hot-swap) it with a new drive of the same model. If not the same model, the new drive must have a capacity equal to or larger than the failed drive. The new disk must have an equal or larger size so that the RAID configuration can be rebuilt. There is no need to turn off the EonNAS system when replacing the drive. The rebuild operation will be executed automatically.
Can I have two or more pools set up with different RAID levels on my EonNAS? For example, RAID 1 for the pool of disk 1&2, RAID 0 for the pool of disk 3&4?
Yes, you can create pools protected by different RAID levels as long as you have a sufficient number of drives.
Can I start using the EonNAS system without installing disk drives in all the drive bays, and install additional drives later when needed?
Yes, you can initialize EonNAS with only two hard disks installed, and install more hard disks later when needed.
However, installing disks in this manner may lead to wasted capacity: when you later install additional hard disks, they need to be either configured as a new pool or configured as a new disk group and added into the original pool.
Can I migrate between RAID levels in a pool? For example, from RAID5 to RAID6 or from RAID1 to RAID5?
EonNAS doesn’t support RAID migration. You have to backup data to a PC or other devices first, recreate the pool, and copy the data back to the new pool.
I currently have a non-EonNAS system with configured disks. Is there a way for me to migrate the disks to the EonNAS system without losing the data?
Every NAS vendor uses its own disk partition layout; therefore the RAID configuration on other NAS systems can not be used on EonNAS directly by swapping the hard drives.
In order to reuse your hard disks currently installed on the non-EonNAS system without losing the data stored on them, you will have to transfer all the data to a temporary storage location, such as a PC. Once the data transfer is completed, setup your EonNAS with these hard disks as RAID and then copy the data from the temporary location.
Can access control be configured for sub-folders?
How can I use anti-virus software to scan data on EonNAS systems?
EonNAS can communicate with scan engines installed with anti-virus software supporting the ICAP protocol. When NFS/CIFS clients try to read a file on EonNAS, EonNAS will query the scan engine and transfer the file for scanning if necessary.
Can access control be configured for sub-folders?
Does EonNAS support iSCSI or FC volume replication?
Yes. Currently users can achieve this with the pool mirror function. The replication enabled by the pool mirror function is block-based, meaning it replicates all the data stored in the EonNAS system, including data is stored in shared folders and iSCSI/FC volumes. By setting one EonNAS as the source and another as the target, all data, including iSCSI and FC volumes, on the source system can be replicated periodically or real-time based on user-configurable policies.
How do I synchronize all data between two different EonNAS systems?
You have two options to synchronize data:
- Pool mirror (pool-based replication). Prepare two identical EonNAS systems and create a mirror pair to synchronize the two pools in the two systems. Synchronization can be done constantly or periodically.
- Remote replication (folder-based replication). Select a folder on one EonNAS system as source and a folder on the other EonNAS system as target. The two folders can be synchronized at scheduled intervals.
Can I use remote replication to backup data between EonNAS Pro models and EonNAS models?
Remote replication supports data backup between models from the same EonNAS group. EonNAS Pro 200, Pro 500, Pro 800 and EonNAS 1100 form a group; EonNAS 3210, 3220, 3230 and 5120 form a group.
I want to back up my data through the Internet. If I setup the EonNAS system behind a firewall, and enable the remote replication function, which port should I open?
The default listening port of ssh is 22 (cannot be changed).
If the EonNAS system experiences an abnormal shutdown, does the remote replication function continue to operate?
If the remote EonNAS system is powered off, network failure occurs, or other abnormal events occur, the remote replication function will stop, and will start again on the next scheduled date and time.
Note: Please enable the "Perform incremental replication" function; with this function, the system will backup only new files.
