Hi. I need to grow a ZFS file system on Leap 42.2. As required I have modified the reservation and quota for the pool, however I'm missing the growfs command I have found by googling (and I can't find it in software.opensuse.org). May I ask for help? Tnx Marco -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Bear in mind that 42.2 reaches EOL in 2 days time (ie, 26 Jan). BC -- Always be nice to people on your way up -- you'll see the same people on your way down. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

You expand zpool by adding vdev (or replacing devices in existing vdev). What exact magic growfs does additionally?

In ZFS a volume not necessarily uses all the space available in a pool, and I'm trying to avoid the autoexpand in order to have under control the space reservation. This means that if the size (called reservation) of the volume is increased the a growfs is required as the autoexpand is off (or seems to be required, maybe I'm doing some think wrong) Marco On 24/01/18 11:10, Andrei Borzenkov wrote:

You expand zfs volume by setting volsize property. growfs expands Solaris UFS filesystem. You need to use whatever tool is appropriate for your zfs volume content.

OK, I'm using the "native" ZFS filesystem, nothing special done. I think the issue is somehow related to the reported size of the file system and the effective size on the volume, as I have enabled the deduplication (factor 33x) where I did my first test. A new test on a non deduplicated pool works without any problem. I will play a little bit with the volsize, reservation and quota to have it working. Tnx!

You are confused. ZFS can have dataset and volume. Dataset is what is presented as filesystem and it has quota and reservation. Volume is presented as block device and it has volsize. If you say "native" zfs it unlikely is volume in which case it also does not have volsize property.

Tnx!
