Sqlite3.operationalerror: Disk I/o Error Ipython
my desktop in cygwin, but fails on our server. I am creating a sqlite disk io error simple database using the sqlite3 module in python. I open a connection con=sqlite3.connect("./file.db") #works cur=con.cursor() #works cur.execute("""create table test(name,

age)""") #fails on server, works on desktop the result: An empty file.db is created, and I get "sqlite3.OperationalError: disk I/O error" on the execute command. If I use ":memory:", the command works sqlite3 nfs fine. For some reason, it is having trouble writing to the disk. The disk is actually some networked file system; not sure if that matters.

There could be any number of reasons. The message is coming from the SQLite library and it is doing that because of something that happened with the operating system. My best guess is that the journal can't be created for some reason. The server may have extra security rules, quotas etc causing this. The easiest way to find the problem is to run the program under strace which will show every system call made and the response.

I ran my python script using strace. It is failing under the fcntl() command. strace says that (Function not implemented). I did a search on google and found the following under

I've been having this problem and I http://dba.stackexchange.com/questions/44156/disk-i-o-error-in-sqlite couldn't find a solution. I have a SQLite3 database, and I'm trying to insert data from a file that contains SQL inserts. Sample data in the file: insert into files (filesize, filedate, md5, fullpath, origin) values (5795096,1370159412, "e846355215bbb9bf5f30102a49304ef1", "SDs/16G-1/DSC00144.JPG", "SDs"); insert into files (filesize, filedate, md5, fullpath, origin) values (5435597,1370159422, "1a7bcf3a4aaee3e8fdb304ab995ff80f", "SDs/16G-1/DSC00145.JPG", "SDs"); insert into files (filesize, filedate, md5, fullpath, origin) values (5121224,1370159432, "16d28e83599c731657a6cd7ff97a4903", "SDs/16G-1/DSC00146.JPG", "SDs"); I tried inserting that in the db file with the following command: $ sqlite3 allfiles.db < insert.sql See below the error that I get: Error: near line 27: disk I/O error Error: near line 28: disk I/O error Error: near line 34: disk I/O error Error: near line 39: disk I/O error Error: near line 47: disk I/O error Error: near line 129: disk I/O error The input lines that don't generate error are successfully included, but I don't understand why some lines have errors, and they are not inserted into the DB. There's nothing special in the lines with error, and if I run the command again I get errors in different lines, which means it's random
