And, i'm an idiot.
My DB version:
PostgreSQL 8.4.9 on x86_64-redhat-linux-gnu, compiled by GCC gcc (GCC) 4.1.2 20080704 (Red Hat 4.1.2-51), 64-bit2011/12/2 Oleg Serov <serovov@xxxxxxxxx>
Hello, i have a problem.
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.
This seems to be an Index corruption. Did you try re-indexing ? Index creation might have failed, re-indexing would re-organize the Index tuples. If you are sure about disk corruption, try and "re-create" or "create concurrent Index" on a different disk.
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
This should be a free space issue, do you have enough space in "pg_stat_tmp" disk ?
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?
What kind of backups you have available ?
Thanks
VB
