We deleted a disk Vdisk_BBDD_50g_023 from ASM diskgroup, but there are two process that lock the physical disk. That's a RAC environment, and we have this problem only in one node.
fuser -a Vdisk_BBDD_50g_023
Vdisk_BBDD_50g_023: 27869 31155
[oracle@tiro mapper]$ ps -ef|grep 27869
oracle 27869 1 0 Mar20 ? 00:01:36 asm_vbg0_+ASM2
[oracle@tiro mapper]$ ps -ef|grep 31155
oracle 31155 1 0 Mar20 ? 00:01:37 asm_vbg2_+ASM2
If we view it from asmcd we view the disk in status candidate.
ASMCMD> lsdsk --candidate -p
Group_Num Disk_Num Incarn Mount_Stat Header_Stat Mode_Stat State Path
0 36 3208863957 CLOSED CANDIDATE ONLINE NORMAL /dev/mapper/Vdisk_BBDD_50g_023
So we can't disconnect the disk of the operating system.
