Hi,
so I've tried the binary distribution for linux and I have these errors
in logfile (I've seen them already under 3.23.41, under which I compressed
the tables):
010910 18:12:20 mysqld started
/usr/local/mysql/bin/mysqld: ready for connections
010910 18:13:52 read_const: Got error 127 when reading table ./Ncrassa/contig_data
Running myisamchk without options does not show any errors. Here are some
details:
$ myisamchk -dvvv /data/mysql/Ncrassa/contig_data.MYI

"CHECK TABLE CONTIG_DATA" says that the table is also OK.
My question is: because I compressed the table under "broken" 3.23.41,
shouldn't I uncpress the table and compress again? Or at least recreate the index.
The problem is, that I don't know how to repeat this problem. I can work with table
(i.e. SELECTs work).
However, the message in logfile is weird. It happens (and happened even
before this upgrade) with other tables:
010910 16:08:04 read_const: Got error 127 when reading table
./Athaliana_II/contig_data
010910 16:12:28 read_const: Got error 127 when reading table
./Campylobacter_jejuni_NCTC_11168/blast_data
You may want to check pub/mysql/secret/compressed.tgz or delete it as
junk. ;) Thanks!
