![]() In this example, we are going from a 100GB to a 200GB volume. ![]() Doing so will simply cut the end of the disk off and will cause data to lose. Systems specs are: Intel (R) Xeon (R) Gold 5222 CPU 3.80GHz, 256Gb RAM, 24x 3,5TB SSDs. Steven Wormuth said: It sits there nestled in with your datasets and uses the space you assign whether it needs it or not. Hey guys, I have some new system on which we installed FreeNas-11.3-U5. It can live on the top-level dataset (which shares the pools name) or in any child dataset. To RSYNC to backup a filesystem you backup it just from the FS standpoint, by pointing at the mount point, not at the block device that you mount there. A zvol is a special type of dataset that provides a block device instead of a filesystem. Ti phn Network, chn vào mc Global Configuration cu hình các thông tin liên. Not a ZFS limitation but an RSYNC limitation. Sau khi vào c màn hình chính, chn vào phn System > General cu hình các thông tin c bn cho server FreeNAS nh: Http port (80). NOTE: This is critical nothing stops you from setting the new size to be smaller than the old size. pure capsaicin Nov 30th, 2009 at 1:26 AM RSYNC is a filesystem tool, it can't copy devices. Zfs get volsize DiskPool0/vol01 :~# zfs get volsize DiskPool0/vol01 We will see “volsize” properties for volumes only, as we can’t see the same for datasets. Zfs list -r DiskPool0 :~# zfs list -r DiskPool0 I used Zpool export on server 1 and then move the drives into server 2. I expected to find an existing post on this but haven't managed to get an answer related directly to moving an array and it's data from from and old FreeNAS server to a new one with a new install. But zvols have to extend by setting the volsize property to a new size. I'm guessing I'm missing something simple here. The ZFS dataset can be grown by setting the quota and reservation properties. Is it possible to mount an NTFS formatted zvol directly to the FreeNAS (eg using some form of mount or ntfs_mount command?), if so what command could I use? I know on Linux I'd use something similar to 'mount -t ntfs /dev/mapper/xxx /mnt/xxx' however I'm not too familiar with FreeBSD or zvols under the hood.Ģ.In ZFS, there are two types of filesystems (datasets and zvol). img file of the zvol which isn't practical in my case due to the data size: ġ. I've found another thread here which outlines a similar case, however the solution in that case was to create a. I am wondering given the zvol is formatted as NTFS inside, could I mount this on the FreeNAS directly and then move the files to my dataset using mv, then perhaps re-apply permissions on the dataset within the FreeNAS GUI to fix up any permissions that may or may not have been migrated from the file copy. For example, if the system has three hard disks, a swap mirror is created from the swap partitions on two of the drives. Tipp: iSCSI geht nur mit einem ZVOL, bei Sicherung über ein Netzwerkshare (SMB/NFS Share) geht hingegen nur ein Dataset. For reliability, FreeNAS creates swap space as mirrors of swap partitions on pairs of individual disks. I have around 150TB to move in total so this would take a large amount of time. When the FreeNAS system runs low on memory, less-used data can be swapped onto the disk, freeing up main memory. I have migrated other smaller LUNs using a Windows Server, however the process is fairly slow and I'm seeing only about 30MB/s on average. Following one of my other posts regarding iSCSI performance issues, I'm now looking for a faster way to migrate my data from an NTFS formatted iSCSI zvol extent to a ZFS dataset.
