Hello everyone.
I replaced the disks in the storage system with 1.2 TB disks with 2.4 TB disks. This is an array with 1 logical disk, on which VMs operate. How can I increase the logical disk using the free space on the disks?
I read that this can be done using the tool - Administration - Background tasks - migration. But I'm not completely sure about this.
Tell me the best way to do this?
This storage system is in operation and not in testing, so I can't experiment.
Hi. I'm doing it through the migration wizard. It seems like it should be like this, but I'm not sure if it's safe for my data on the disk I want to expand?
Another question: if I have RAID 10 and I set the target RAID 5 in the master, does the system reconfigure RAID 5 from the same physical disks or do I need a new array of physical disks? If this is just reconfiguring a RAID from one to another on the same physical disks, is my data in danger during this operation?
Yes, you can also migrate from WebPAM.
Be advised that once started, the migration cannot be stopped or paused. And it can take a long time.
You should be able to migrate from RAID10 ro RAID5 as the RAID5 will be larger than a RAID10 with the same number of disk.
The Product manual has some useful information about migration...
RAID Level Migration
To migrate a disk array is to do one or both:
• Change its RAID level
• Increase the number of disk drives (sometimes called Expansion)
On VessRAID, RAID level migration is performed on the disk array but it applies
to the logical drives. Migration takes place on an existing Functional disk array
without disturbing the existing data. While the disk array is migrating, you can
access the data as before. When migration is complete, your disk array will have
a different RAID level and/or a larger capacity.
In most cases, you must add one or more physical drives during the migration
process. You can never reduce the number of physical drives.
The tables below show the migration options for a source logical drive according
to its RAID level. The available target RAID levels are shown with their
requirements.
See “Migrating a Disk Array” on page 122 or page 165.
