Dear All,
The stats file in pg_stat_tmp are getting corrupted. Even earlier the files in pg_stat got corrupted. They show ?? ?? when you list the files in folder. Also we can see them in the error log.
it says " could not open statistics file 'pg_stat_tml/db_0.tmp': to 'pg_stat_tmp/db_0.stat': Input/output error".
After doing e2fsck (file system scan ) it is fixed but that needs downtime and also it removes the file. What is the impact if the file is being removed ?
Has anybody faced such issue or can guide me what can be done and how it can be avoided in near future ?
Thanks and Regards,
Devendra Yadav
