Bug Minor Resolved Fixed Etienne Aujames Tommi Tervo easy Mon, 15 Jul 2019 17:02:42 +0000 Sun, 8 Aug 2021 06:44:48 +0000 Sat, 11 Jul 2020 16:02:57 +0000 Lustre 2.10.7 Lustre 2.14.0 0 5 <p>(too tired, managed to put description to the env-field)</p> <p>Project quota pid overflows somewhere between 4.2M and 4.3M without warning.</p> <ol> <li>lfs project -p 4210007132 /users/tervotom</li> <li>lfs project -d /users/tervotom<br/> 4210007132 - /users/tervotom<br/> lfs project -p 4310007132 /users/tervotom<br/> lfs project -d /users/tervotom<br/> 15039836 - /users/tervotom</li> </ol> <p>From your examples, the project ID is overflowing at 2^32-1 = 0xffffffff =4294967296, somewhat over 4B, not 4M:</p> <div class="preformatted panel" style="border-width: 1px;"><div class="preformattedContent panelContent"> <pre>$ printf "%x\n" 4210007132 faef9c5c $ printf "%x\n" 4210007132 faef9c5c $ printf "%x\n" 4310007132 100e57d5c $ printf "%d\n" 0xe57d5c 15039836 </pre> </div></div> <p>so this is totally expected because the on-disk and network data structures only store a 32-bit value for projid.</p> <p>I guess the issue is that "<tt>lfs project -p</tt>" should report an error when a user provides a project ID larger than 2^32-1.</p> <p>Error message would be preferable.
