Обсуждение: help for pg_wal issue
Hi,
I want to backup my postgresql database but it fails because it is looking for some wal files on pg_wal directory.
Before backup I checked my pg_wal directory and I saw the wal file,
bash-4.2$ cd /pgdata/pgsql/data/pg_wal
bash-4.2$ ls
-rw------- 1 postgres postgres 16777216 Jun 24 01:01 000000010000000A000000AE
-rw------- 1 postgres postgres 16777216 Jun 24 01:01 000000010000000A000000AF
-rw------- 1 postgres postgres 16777216 Jun 24 01:01 000000010000000A000000B0

-rw------- 1 postgres postgres 16777216 Jun 24 01:31 000000010000000A000000B6
-rw------- 1 postgres postgres 16777216 Jun 24 01:46 000000010000000A000000B7
But backup fails with,
Failed to open: /pgdata//pgsql/data/pg_wal/000000010000000A000000AE
Error! The backup has failed.
After I checked pg_wal directory and really there is no such file, it was not appear on disk. What can I do for this? Please help..
bash-4.2$ cd /pgdata/pgsql/data/pg_wal
bash-4.2$ ls

wal_level = replica
wal_keep_segments = 50
archive_mode = on # enables archiving; off, on, or always
archive_command = 'cp %p /pgdata/arc' # command to use to archive a logfile segment
archive_timeout =0 # force a logfile segment switch after this
