mount -t nfs: Segmentation fault

Dne 2016-03-15 20:24

Tak jsem dnes koupil USB3 rámeček a dva disky a nakonfiguroval je jako RAID1.
Teď chci překopírovat data ze staré NASky, ovšem pokus o její připojení selhal:

turris /mnt/nsa210 # mount -t nfs 192.168.1.106:/i-data/6193b895/nfs/backup /mnt/nsa210/backup/
Segmentation fault

v dmesg je tohle:

Další pokus o připojení pak zůstal viset. Asi budu muset restartovat Turris.
Netušíte někdo, v čem je problém?

Díky,
