QUESTION

ZFS send single snapshot including descendent file systems

Asked 2022-Apr-03 at 10:44

Is there a way to send a single snapshot including descendant file systems? 'zfs send' only sends the the top level file system even if the snapshot was created using '-r'. 'zfs send -R' sends the descendant file systems but includes all the previous snapshots, which for disaster recovery purposes consumes unnecessary space if the previous snapshots are not needed in the disaster recovery pool.

Answered 2022-Mar-10 at 20:23

No.

If you want the entire filesystem for disaster recovery, you need the entire filesystem.

A ZFS snapshot is not a complete filesystem. It's effectively the difference between it and the previous snapshot, and that chain continues all the way back through all the snapshots to the "base" copy of the filesystem.

You can send incremental snapshots, which only send the differences. Per Oracle ZFS documentation:

...

If you are sending the snapshot stream to a different system, pipe the zfs send output through the ssh command. For example:

variable derived js object property

Asked 2022-Jan-24 at 18:06

I need to add properties to a JS object in QML. I don't know the properties in advance. So I am stuck.

I found this topic with same issue: QML defining an object property

The only way to solve this coming up in my mind is to create a QMap on C++ side and to pass it back to QML.

Any other suggestions using JS?

QUESTION

restart of the smbd daemon without interrupting the load on the windows client

Asked 2021-Sep-13 at 09:44

Such a problem, there is a server (cluster) on which smb is used, the server is entered into the AD domain, sometimes it is necessary to restart the smbd service (reload won't fit), but at the same time there is some copying of the file on the client (windows), then the load is interrupted, and after the klick "Retry" button, the download starts from the very beginning. Is it possible to do something like that so that the load continues to go from the moment where it was interrupted, maybe you need to configure the client like that. client connects as SMBv3 or SMBv2

ANSWER

Answered 2021-Sep-13 at 09:44

Resuming a copy operation doesn't depend on the smb client or server, but on the application which is doing the copying.

The standard Windows copy doesn't know to resume.

Other (third party) apps (maybe Total Commander?) can be more intelligent about it. You could even write your own app to do a smart copy.

Quotes and slashes surviving multiple layers

Asked 2021-Jun-26 at 19:30

Goal I need to effectively run a copy (cp) command but have explicit quote symbols preserved. This is needed so that the z/OS Unix System Services Korn shell properly recognizes the target of the copy as a traditional MVS dataset.

The complexity is that this step is part of an automated process. The command is generated by Perl. That Perl is executed on a separate Docker container via ssh. This adds another layer of escaping that needs to be addressed, in addition to the escaping needed by Perl.

Basically, docker is doing something like

mkfs.vfat: unable to open {partition}: No such file or directory (command succeeds, but throws this error and blocks rest of script)

Asked 2021-May-21 at 03:38

Update: I got this working but am still not 100% sure why. I've appended the fully and consistently working script to the end for reference.

I'm trying to script a series of disk partition commands using sgdisk and mkfs.vfat. I'm working from a Live USB (NixOS 21pre), have a blank 1TB M.2 SSD, and am creating a 1GB EFI boot partition, and a 999GB ZFS partition.

Everything works up until I try to create a FAT32 filesystem on the EFI partition, using mkfs.vfat, where I get the error in the title.

However, the odd thing is, the mkfs.vfat command succeeds, but throws that error anyway and blocks the rest of the script. Any idea why it's doing this and how to fix it?

It may take time for kernel to be notified about partition changes. Try calling partprobe before mkfs, to request kernel to re-read the partition tables.
