We have a few Postgres 16.2 servers running on VMs (RHEL 9.3) created on
VMware vSphere (7.0.3). 3PAR LUNs are used as their storages.
On a couple of the PostgreSQL servers, there are errors such as:
ERROR: could not read block 1264 in file "base/16520/59258": read only 0
of 8192 bytes
The errors occured when trying to insert rows to the tables.
The blocks belong to tables. For instance,
select relname, relkind from pg_class where relfilenode = '59258';
relname | relkind
---------------+---------
smallgroupset | r`
I can pg_dump the all the rows of the table smallgroupset and there is no
data loss.
pg_dump -d tabula -t smallgroupset -f smallgroupset.sql -v >
smallgroupset.log 2>&1
I've tried to reindex the table ( and the whole database) but it made no
difference.
Can anyone advise the root cause of the errors?
Any help will be much appreciated.
