[Lustre-discuss] mkfs.lustre resize maximum

[Andrus, Brian Contractor]

All,



I am trying to reformat an OST which was originally created with lustre 2.3 with lustre 2.4 mkefs.lustre.



Command:

mkfs.lustre --reformat --ost --index=0 --fsname=WORK --mgsnode=10.100.1.10 at o2ib /dev/VG_Lustre/WORK_OST0

   Permanent disk data:
Target:     WORK:OST0000
Index:      0
Lustre FS:  WORK
Mount type: ldiskfs
Flags:      0x62
              (OST first_time update )
Persistent mount opts: errors=remount-ro
Parameters: mgsnode=10.100.1.10 at o2ib

device size = 16776956MB
formatting backing filesystem ldiskfs on /dev/VG_Hamming/WORK_OST0
        target name  WORK:OST0000
        4k blocks     4294900736
        options        -J size=400 -I 256 -i 524288 -q -O extents,uninit_bg,dir_nlink,quota,huge_file,flex_bg -G 256 -E resize=4290772992,lazy_journal_init -F
mkfs_cmd = mke2fs -j -b 4096 -L WORK:OST0000  -J size=400 -I 256 -i 524288 -q -O extents,uninit_bg,dir_nlink,quota,huge_file,flex_bg -G 256 -E resize=4290772992,lazy_journal_init -F /dev/VG_Hamming/WORK_OST0 4294900736
   The resize maximum must be greater than the filesystem size.

   Bad option(s) specified:

   Extended options are separated by commas, and may take an argument which
        is set off by an equals ('=') sign.

   Valid extended options are:
        stride=<RAID per-disk data chunk in blocks>
        stripe-width=<RAID stride * data disks in blocks>
        resize=<resize maximum size in blocks>
        lazy_itable_init=<0 to disable, 1 to enable>
        lazy_journal_init=<0 to disable, 1 to enable>
        test_fs
        discard
        nodiscard
        quotatype=<usr OR grp>


mkfs.lustre FATAL: Unable to build fs /dev/VG_Hamming/WORK_OST0 (256)

mkfs.lustre FATAL: mkfs failed 256



I see some bugs from lustre 1.8 (LU-399) referencing the error, but nothing for 2.4

Maybe it is how I am trying to make the filesystem that is causing grief.

Can anyone provide some input/advice here?



Thanks in advance,
