💖 lfs-getdirstripe — bestie's guide to peeking at directory layouts 💖

okay so you're here because you want the tea on lfs getdirstripe, part of the Lustre User Utilities. It's the lfs(1) command that spills the layout pattern of a given directory, no cap. 🫶

✨ NAME ✨

lfs-getdirstripe — list the layout pattern of a given directory

🌸 SYNOPSIS 🌸

lfs getdirstripe [-cDhHimOrRTvXy]...  DIR...

💅 DESCRIPTION 💅

So basically: this one gets you the layout pattern of striped directories. It's a lfs(1) command, and it's lowkey the sibling of lfs getstripe, except it's specifically for the directory layout, not the file one. Directory vibes only, periodt. 🎀

👑 OPTIONS 👑

  • -c, -T, --mdt-count — just show how many MDTs the directory is striped across. That's it, that's the whole thing.
  • -D, --default — shows the default layout that gets used when new subdirectories are created.
  • -F, --fid — show only the 128-bit unique Lustre File Identifier (FID). just the FID, nothing else, she's minimal like that.
  • -h, --help — prints the usage message. our little helper 🧚
  • -H, --mdt-hash — only show the hash function being used for this directory. It also shows hash flags, like overstriping (>1 stripe per MDT), iykyk.
  • --hex-idx — print MDT indexes in hexadecimal instead of decimal. hex girlies rise 🌈
  • -i, -m, --mdt-index — only show the master MDT index of the directory.
  • -O, --obd=FSNAME-MDTnnnn_UUID — limits the returned directories to the ones with objects on a specific MDT, whose UUID is FSNAME-MDTnnnn_UUID.
  • -r, --recursive — the default behavior when you hand it a directory is to list the striping info for all the sub-directories inside that directory. Adding --recursive expands that and recurses into all subdirectories. yes bestie, all the way down 😭
  • -R, --raw — print the MDT index in raw format, without converting it to a name.
  • -v, --verbose — print verbose info about the directory striping. she's chatty 💬
  • -X, --max-inherit — show the inherit depth of default layout.
  • -y, --yaml — show the layout in YAML format for easier parsing. parser-friendly, iconic. ✨
  • --max-inherit-rr — show the inherit depth of default layout to roundrobin mkdir.

🌟 EXAMPLES 🌟

List the striping information of sub-directories, that are located on MDT1, under /mnt/lustre/dir1:

# lfs getdirstripe -O lustre-MDT0001_UUID -r /mnt/lustre/dir1

🦋 AVAILABILITY 🦋
