Replace OSDs and Journal Disks
You can replace failed storage devices on storage nodes.
For best results, ensure the replacement disk is the same size as others in the same peer group. Do not substitute a smaller disk than the original.
Note
Due to a limitation in udev, the device path of a disk connected through a SAS controller changes when the disk is replaced. Therefore, in the general procedure below, you must lock, delete, and re-install the node. However, for standard, , and systems, use the following alternative procedures to replace without reinstalling the host:
Replace OSDs on a Standard System <replace-osds-on-a-standard-system-f3b1e376304c>Replace OSDs on an AIO-DX System <replace-osds-on-an-aio-dx-system-319b0bc2f7e6>Replace OSDs on an AIO-SX Multi-Disk System <replace-osds-on-an-aio-sx-multi-disk-system-b4ddd1c1257c>Replace ODSs on an AIO-SX Single Disk System without Backup <replace-osds-on-an-aio-sx-single-disk-system-without-backup-951eefebd1f2>Replace OSDs on an AIO-SX Single Disk System with Backup <replace-osds-on-an-aio-sx-single-disk-system-with-backup-770c9324f372>
Follow the procedure located at : Change
Hardware Components for a Storage Host <changing-hardware-components-for-a-storage-host>.
The replacement disk is automatically formatted and updated with data when the storage host is unlocked.
