[Lustre-discuss] OSS Node Hard Disk Changing Procedure

[VIJESH EK]

Dear Sir,
**
We have a HPC setup with four OSS server(OSS1 to OSS4) and two MDS
Nodes(MDS1 to MDS2)
OSS1 & OSS2 ,OSS3 & OSS4 clustered each other
In OSS4 logs i am getting the following   "unreadable" error continuously.
So yesterday i runned fsck
and fixed some errors . Today the same type of error is comes again
continuously.

Feb 26 06:24:43 oss4 smartd[9306]: Device: /dev/sda, 2 Currently unreadable
(pending) sectors
Feb 26 06:54:43 oss4 smartd[9306]: Device: /dev/sda, 2 Currently unreadable
(pending) sectors
Feb 26 07:24:43 oss4 smartd[9306]: Device: /dev/sda, 2 Currently unreadable
(pending) sectors

/dev/sda is a local hard disk. So i desired to  change the local hard disk
of the OSS4 server
I required a help from lustre team for the the easiest way to change the
HDD in OSS Node.
The server is running now,so can  anybody suggest me the procedure to
change the HDD in OSS servers ?
