This is parted calling _mount_table_search via _partition_is_mounted_by_dev in libparted/arch/linux.c over and over again. *** This bug has been marked as a duplicate of bug 353191 *** |
Description of problem: During a fresh install, this sequence of discovering that there is no swap space is repeated 2395 times: ----- (from strace) 719 open("/proc/swaps", O_RDONLY) = 14 719 fstat(14, {st_mode=S_IFREG|0444, st_size=0, ...}) = 0 719 mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x2aaac2514000 719 read(14, "Filename\t\t\t\tType\t\tSize\tUsed\tPrio"..., 1024) = 37 719 stat("Filename", 0x7fff3f67cd00) = -1 ENOENT (No such file or directory) 719 read(14, "", 1024) = 0 719 close(14) = 0 719 munmap(0x2aaac2514000, 4096) = 0 ----- Instead, the information that there is no swap space should be cached. Version-Release number of selected component (if applicable): anaconda-11.3.0.45-1 How reproducible: always Steps to Reproduce: 1. fresh install from DVD 2. as soon as vtty2 is available during the install: strace -f -o '|gzip' -q -p <pid-of-anaconda> > strace.out & (you must suppy 'strace' on a USB flash memory device before boot, and do the mount yourself.) 3. inspect strace.out (63MB compressed, 1GB uncompressed) for: open("/proc/swaps") and stat("Filename"). Actual results: 2395 repetitions of discovering that there is no swap space Expected results: remember after the first time. Additional info:
