I'm having a pretty serious issue with 200906 with simple operations that used to work fine on nv_79. The problem I'm trying to solve right now are FTP transfers from a ZFS filesystem using proftpd as a server that pause for over ten minutes with no discernible cause. When the transfer hangs, this is the truss output:
811: write(1, " 1 5 0 O p e n i n g ".., 83) = 83 811: close(11) Err#9 EBADF 811: sigaction(SIGURG, 0x080479E0, 0x00000000) = 0 811: sigaction(SIGURG, 0x00000000, 0x08047A00) = 0 811: sigaction(SIGURG, 0x080479A0, 0x00000000) = 0 811: brk(0x08188B08) = 0 811: brk(0x08194B08) = 0 811: fcntl(7, F_SETLKW64, 0x080D3520) = 0 811: llseek(7, 16, SEEK_SET) = 16 811: write(7, " +03\0\0 aEA\0\0FEFF\0\0".., 520) = 520 811: llseek(7, 16, SEEK_SET) = 16 811: fcntl(7, F_SETLKW64, 0x080D3520) = 0 811: setsockopt(13, tcp, TCP_CORK, 0x08047AC4, 4, SOV_DEFAULT) = 0 811: fcntl(13, F_GETFL) = 2 811: sendfilev64(1, 13, 0x08047A30, 1, 0x08047A24) (sleeping...) ...and then takes at least 10 minutes to do something. Then another transfer starts, and it happens again. Only a few meg gets transferred between pauses. How can I begin to troubleshoot this? Is there something specific I should be looking at? Despite sendfilev64, is this even a ZFS issue? -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
