Informix - Problem description

Problem IT30644 Status: Closed

ADDING A CHUNK CAN FAIL WITH ERRNO 4 (FALLOCATE() INTERRUPTED BYALARM)

product:
INFORMIX SERVER / 5725A3900 / E10 - 
Problem description:
If addition of chunk file takes too long (longer than two to
four seconds), this now can fail with errno 4 (Interrupted
system call).

$ onspaces -c -d testdbs -p /path/to/new/chunk -o 0 -s

Verifying physical disk space, please wait ...
Chunk verification failed with errno 4.

This would happen if that file hasn't been preallocated, so
would be allocated using fallocate() api.
