Yichun, December 26 (Rain) 25th this day, Jiangxi Yichun College is said to be "graced", this year, the newly elected academician of the Chinese Academy of Sciences Chen Xianhui back to his alma mater. At the symposium, Chen Xianhui that year's teacher came, his classmate friends came, we share Chen Xianhui that year in school experience. At the same time, Chen Xianhui also spoke at the symposium, he said, now achieved and his

Finally, I pulled the seats to the floor to sleep, and woke up again in the middle of the night. If Xi Zi in Sichuan is so hot, it is estimated that the temperature is above 40 degrees. In Suining, his hometown is becoming more and more friendly. There are two famous thi

PrefaceAPP Scenario Description:When you are unable to plan your storage properly, the storage re-planning (eg, one or several apps that write bigdata for a certain LV-mount point in a post-maintenance job may soon be out of space for your LV mount point, but it's worth noting that Does your other LV mount point have a large storage space? Basically not applied t

1. Expand LV capacity You do not need to detach the file system to increase the LV capacity. The procedure is as follows: A. Use fdisk to set partitions with 8e System ID B. Create a PV using pvcreate C. Use vgextend to add PV to VG to resize VG D. Use lvresize to add the PE of the new PV to the LV. E. Increase the file system capacity through resize2fs. Example

In Aix, The lvcb information of LV is located at 512 bytes of each LV header, and a copy of all LV lvcb is also available in vgda, if the lvcb of the LV header is inconsistent with the lvcb in vgda, how can we synchronize it? However, this situation is rare, but it only provides a way of analyzing problems. If there is

Environment first: AIX7.1OracleASM11.2.0.3 the size of flashdg in ASM needs to be increased to 35 GB in the current test environment ), diskgroup is created based on the lv divided in raw mode in vg. Since the test environment only notifies the AIX administrator, the AIX administrator increases the number of pp of fsflashdglv through smitlv. First, let's explain the environment: AIX 7.1 Oracle/ASM 11.2.0.3. In this test environment, we need to increas

physical volumes of the subordinate. It can be seen that the volume group size is the total size of all physical volumes in the volume group. The vgcreate command can create a volume group, and vgextend can add a physical volume to a volume group. PE: The physical disk area is the smallest storage unit used for management in the volume group. The size is determined when the volume group is created. Once the volume group is created, its PE size is fixed and unchangeable, the default PE size is 4

Environment first: AIx 7.1 Oracle/ASM 11.2.0.3 Single Instance In this test environment, the flashdg size in ASM needs to be increased to 35 GB (currently 10 Gb). diskgroup is created based on the LV divided in RAW mode in VG. Because only the AIX administrator is notified in the test environment, the AIX administrator increases the number of PP of fsflashdglv through Smit LV. After adding the number, you c

11.11) change the LV size. For example, to change the 800 mb LV to 800 mb: # lvextend-l 800/dev/vg01/lvdata, note: Here-l 800 means to expand "to" MB, instead of expanding by 800 mb, it is still not completed. To expand the file system, you can refer to the following methods: # umount/dev/vg01/lvdata # Extendfs-F vxfs/dev/vg01/lvdata # Mount/dev/vg01/lvdate B. Delete the original

Steps:(1) add a new 8e systemID partition;(2) use the pvcreate command to construct the PV;(3) use the vgextend command to add PV to vg_1;(4) Use the lvresize command to add the PE in the newly added PV to lv_1;(5) Use the resize2fs command to expand the LV capacity to the entire file system;(1) add a new 8e systemID partition. Since the previous four primary partitions are created, if you want to create another partition, delete/dev/sdb4, create an e
