[root@localhost ~]# fdisk /dev/sdp Welcome to fdisk (util-linux 2.23.2). Changes will remain in memory only, until you decide to write them. Be careful before using the write command. Device does not contain a recognized partition table Building a new DOS disklabel with disk identifier 0x14650e5b. The device presents a logical sector size that is smaller than the physical sector size. Aligning to a physical sector (or optimal I/O) size boundary is recommended, or performance may be impacted. Command (m for help): n Partition type: p primary (0 primary, 0 extended, 4 free) e extended Select (default p): Using default response p Partition number (1-4, default 1): First sector (2048-62914559, default 2048): Using default value 2048 Last sector, +sectors or +size{K,M,G} (2048-62914559, default 62914559): Using default value 62914559 Partition 1 of type Linux and of size 30 GiB is set Command (m for help): w The partition table has been altered!

想要启动时自动挂载XFS分区在/zvol_redo上，加入下列行到/etc/fstab：
/dev/sdp1 /zvol_redo xfs defaults 0 1 增加一个logfile 的member alter database drop logfile member '/lvm_redo/redo22.log'; alter database drop logfile member '/lvm_redo/redo32.log'; alter system switch logfile; alter database drop logfile member '/lvm_redo/redo12.log'; alter database add logfile member '/zvol_redo/redo12.log' to group 1; alter database add logfile member '/zvol_redo/redo22.log' to group 2; alter database add logfile member '/zvol_redo/redo32.log' to group 3; set linesize 200 col member form a30 select * from v$log; select * from v$logfile; [oracle@localhost ~]$ ll /zvol_redo/ total 6291468 -rw-r-----. 1 oracle oinstall 2147484160 8月 31 15:32 redo12.log -rw-r-----. 1 oracle oinstall 2147484160 8月 31 15:32 redo22.log -rw-r-----. 1 oracle oinstall 2147484160 8月 31 15:32 redo32.log [oracle@localhost ~]$
