Mazani oddilu

Tak smazat to jde. Postup je nasledujici:

Nejdriv je vhodne se podivat na seznam zarizeni + handleru (prakticky asi vzdy vdisk_fileio) 

scstadmin -list_device

Potom nechat smazat: 

scstadmin -close_dev xen-ferenczy -handler vdisk_fileio

Coz ale nejspis nepujde, nicmene to vypise seznam, co to pouziva. Pokud je prazdny, neni co by se rozbilo a lze pouzit -force 

scstadmin -close_dev xen-ferenczy -handler vdisk_fileio -force

Potom je uz normalne mozne smazat LV: 

lvremove /dev/vg_fc/xen-ferenczy

Zmena velikosti

Server: 

 lvextend -L +1G /dev/fc_eva/xen-skoleni-1
 scstadmin -resync_dev xen-skoleni-1

Podotykam, ze mapovani pres sekci 'fileio je zrovna v tomto pripade 1:1, tj. xen-skoleni-1 → /dev/fc_eva/xen-skoleni-1

Client: 

 echo 1 >/sys/block/sddu/device/rescan
