[Lustre-discuss] OSS Node Local Hard Disk Problem

[VIJESH EK]

*Dear Sir,*
*
*
*We have a HPC setup with four OSS server(OSS1 to OSS4) and two MDS
Nodes(MDS1 to MDS2)*
*It has been running till yesterday without any problem. Today morning i
found that OSS4 is in *
*shutdown condition. I have verified the OSS3 logs and found that it has
been got to fencing state*
*I have again switched on OSS4  now its running*
*
*
*In OSS4 logs i saw some  "unreadable" error as mentioned below*
*
*
*
Feb 26 04:24:43 oss4 smartd[9306]: Device: /dev/sda, 2 Currently unreadable
(pending) sectors
Feb 26 04:54:43 oss4 smartd[9306]: Device: /dev/sda, 2 Currently unreadable
(pending) sectors
Feb 26 05:24:43 oss4 smartd[9306]: Device: /dev/sda, 2 Currently unreadable
(pending) sectors

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. Is it possible the Node fencing is due to
this error ?
While running the e2fsck will resolve this issue ?

*
*Herewith i have attached the /var/log/messages of OSS3 and OSS4*
*can anybody please analyse the log file and kindly assist me what to do ? *
*
*
*
*
*
*
*Thanks & Regards
