I've got a production server, working fine. Then i've got strange error: > ERROR: right sibling's left-link doesn't match: block 147 links to 407 instead of expected 146 in index "order_status_key"' And decidet to backup all server. So i shut-down VPS with server and backup all data. Then, after i booted it - and then - i've got Data loss.
I've lost data, that have been written to DB around 10-100 hours (different tables, have different last updated value).
Then i've analyzed log, and found this: 7 days ago appears this errors: db= LOG: could not rename temporary statistics file "pg_stat_tmp/pgstat.tmp" to "pg_stat_tmp/pgstat.stat": db= WARNING: pgstat wait timeout ERROR: missing chunk number 0 for toast value 2550017 in pg_toast_17076
5 days ago: a lot of: ERROR: xlog flush request F/DC1A22D8 is not satisfied --- flushed only to F/526512E0 83238 db= WARNING: could not write block 54 of base/16384/2619 83239 db= CONTEXT: writing block 54 of relation base/16384/2619
And today: 18 db= LOG: could not open file "pg_xlog/000000010000000F00000052" (log file 15, segment 82): 19 db= ERROR: xlog flush request F/DC1A22D8 is not satisfied --- flushed only to F/52FDF0E0
There is any ability to recover fresh data from database?
