zxfer resuming unneeded disks from sleep #26

Open petr-fischer opened 8 years ago

petr-fischer commented 8 years ago

Hello, I have 3 ZFS pools on home server (zroot, zusbbackup, zmirror) and I am backuping FreeBSD system (zroot) to the USB drive (zusbbackup) with this cron job:

zxfer -dFPv -R zroot zusbbackup/backups/pf-server

I am putting my big media mirror (zmirror) to sleep after 40 minutes of inactivity. But - when zxfer starts (zroot -> zusbbackup), my zmirror disks are resumed - I don't want to even touch the zmirror pool by zxfer while backuping different zpools.

Is possible, that zxfer in some internal command call ZFS function, that acts over ALL zpools (some internal snapshot listing or something)?

Any idea?

Thanks very much!

Yes, it does 'zfs list' across everything at the start of the replication

@petr-fischer could you share how you put disks or pools to sleep? Thx

@cedrictineo by setting timeout (in /etc/rc.local) [FreeBSD]
